Original proving

This is another of the remedies introduced by Swan. The full pathogenesis appears in Med. Visitor, Aug., 1893, part having already appeared in H. W., xviii. 15l. The greatest number of the symptoms were experienced in the head and eyes, and many of these have been confirmed.

Description of the substance

Cat's Milk:
An old cat laps as much milk as a young (England). The cat is a holy creature until the milk arrives (India).
Milk is food for baby mammals. This connection between cat and milk shows us that cats (like us human beings) like milk beyond the state of being babies… They are also showing a childlike behaviour while being adult: being playful, sleeping a lot, their kneading behaviour (pushing their toes in your belly…), sucking on things and dribbeling etc.

Cat's milk contains almost three times as much protein as cow's milk. Orphan kittens fed only cow's milk will not survive because they are not getting sufficient protein in their diet. Also special for cat's milk is the component taurine: it is not present in other milks and is essential for cats (even in their normal diet. For more information about taurine see the chapter about 'food').
The milk composition changes during lactation. There is a tendency toward increasing amounts of crude ash, mainly because of increasing concentrations of calcium. The calcium/phosphorus ratio increases during the lactation period then it decreases again (around 50 days). There was also a slight increase in the dry matter content, whereas iron and vitamin A tended to decrease. As already stated cat's milk contains taurine in adequate amounts (0.30 ± 0.06 g/kg milk); the dominant amino acid is glutamic acid (9.85 ± 1.06 g/kg milk) followed by leucine and aspartic acid. The fat of cat's milk is composed mainly of unsaturated, long-chain fatty acids and, unlike bitch or cow's milk, contains arachidonic acid as well as linoleic acid. Cat's milk was even used in the human kitchen! (see 'traditional use' for more information.)

Composition of milks:
Species    % DM            % fat    % protein    % sugar    % ash
cat                       -         7,9-10.8    10,6-11,4       3.7-7,8       1.0
pig                    20.1          8.3           5.6          5.0           0.9
cow                   12.4        3.7-3,9        3.2-3,5       4.6-4,9       0.7
dog                    22. 7      8,3-9.5          7.5                      3.8                   1.1
human        12.4          4.1          0.8                      6.8                   0.2
(The differences in this list come from different studies: Some tested milk specially at mid-lactation. DM = dry matter.)

Two milk laws of cat Physics:
Law of Milk Consumption: A cat will drink her weight in milk, squared, just to show you she can.
Law of Fluid Displacement: A cat immersed in milk will displace her own volume, minus the amount of milk consumed.

There is also a plant called 'cat's milk':
Cymbocarpa refracta Miers

Reproduction (inclusive lactation):
Female cats, also called queens, generally reach sexual maturity between four and twelve months of age. Male cats, also called toms, usually become fertile between six and eight months of age.
Female cats are "polyestrous," which means they may have many heat (= estrus) periods over the course of a year. A heat period lasts about 4 to 7 days if the female has mated; if she has not, the heat period lasts longer (up to 3 weeks) and recurs at regular intervals after 1-2 weeks. The signs of heat are different in cats as compared to dogs. Cats have minimal vaginal bleeding, usually not even enough to be detected.  Their behaviour is the most notable sign. Cats become very affectionate. They rub against their owners and furniture and constantly want attention. They roll on the floor and they also become very vocal.
Cats are induced ovulators. This means that the act of mating stimulates the ovaries to release eggs.  Therefore, the female's eggs are released from the ovaries when the sperms are deposited in the reproductive tract. The queen will signal her willingness to mate with a unique posture: head down, forelegs bent, rear quarters raised to expose the vulva ( this raised posture is called lordosis), with the tail raised and held to the side of the body, all designed to accomodate entry by the tom cat's penis. Her rear legs will tread rhythmically, as if walking in place. The tom cat will mount the female from the rear, holding her on the back of the neck with his teeth. This biting behavior may in part be to ensure cooperation, but may also stimulate a part of the female's brain that induces ovulation. Whole male cats have barbed penises (much like a fishhook), and upon withdrawal, the female cat will often scream (whether from ecstasy or pain is questionable). It is also believed that the barbed penis and maybe even the scream stimulates ovulation. Most female cats require 3-4 mounts within a 24 hour period for ovulation to occur. Therefore female felines are "superfecund," which means that each of the kittens in her litter can have a different father.

A female cat will be pregnant for approximately 9 weeks - between 60 and 67 days from conception to delivery. Most develop an unusually sweet and loving disposition and demand more affection and attention.  However, some may become uncharacteristically irritable. Some experience a few days of vomiting ("morning sickness") followed by the development of a ravenous appetite which persists throughout the pregnancy. During the latter stages of pregnancy, the expectant mother begins to look for a secure place for delivery. Many become uncomfortable being alone and will cling closely to their owner.  At the onset of labour, many nervously seek a place to make the "nest" or birthing place.  If the cat is attached to her owner, she will not want to be left alone at the time of delivery. If left alone, she may delay delivery until the owner returns.

The signs of impending labor generally include nervousness and panting. The cat will often quit eating during the last 24 hours before labor. She will also usually have a drop in rectal temperature below 100ºF (37.8ºC). The temperature drop may occur intermittently for several days prior to delivery, but it will usually be constant for the last 24 hours.     
Delivery times will vary. Shorthair cats and cats having slim heads, such as Siamese, may complete delivery in one to two hours. Domestic body type cats (having large, round heads) generally require longer delivery times. Persian and other domestic body type kittens tend to be very large and have sizable heads that make delivery more difficult.
Kittens are usually born with first their head. However, it occurs that the kitten is delivered with his tail first and this is considered to be normal as well. The queen's tongue is used to tear the sac and to expose the mouth and nose. Following delivery, the mother will lick the newborn's face. She will then proceed to wash it and toss it about. This vigorous washing stimulates circulation, causing the kitten to cry and to start with breathing; it also dries the newborn's hair coat. The mother will sever the umbilical cord by chewing it about 3/4 to 1 inch (1.9 to 2.5 cm) from the body. Next, she will eat the placenta. It is not uncommon for one or two kittens in a litter to be stillborn. After delivery of the last kitten, most queens settle back to nurse the kittens.

Kittens locate a teat to nurse by pulling with their front legs, paddling with their rear legs and turning their head from side to side. Rhythmic kneading of a kitten's front paws stimulates milk production. This kneading behaviour continues in adult cats and is associated with contentment.
The mother will spend most of her time with the kittens during the next few days. The kittens need to be kept warm and to nurse frequently. Kittens should eat or sleep 90% of the time during the first two weeks. If they are crying during or after eating, they are usually becoming ill or are not getting adequate milk. A newborn kitten is very susceptible to infections and can die within 24 hours. For the first several weeks, the queen licks the anogenital region of each kitten to stimulate urination and defecation. The kittens are born with their eyes closed, but they will open in 7 to 14 days. They should double their birth weight in about one week. At two weeks of age, kittens should be alert and trying to stand. At three weeks, they generally try to climb out of their box. At four weeks, all of the kittens should be able to walk, run, and play. Kittens should begin eating solid food about 3 to 4 weeks of age (other sources say around six to eight weeks). They will eat small amounts as often as 12 times during the day. Sometimes kittens weaned too early will develop lifelong habits of sucking and chewing.
Milk Fever Eclampsia or milk fever is a depletion of calcium from the mother due to heavy milk production. It generally occurs when the kittens are 3-5 weeks old (just before weaning) and most often to mothers with large litters. The mother has muscle spasms resulting in rigid legs, spastic movements, and heavy panting. This can be fatal in 30-60 minutes, so a veterinarian should be consulted immediately.  
If the mother feels the kittens are in danger or if there is too much light, she may become anxious.  There is a type of mother who has been known to kill her kittens as a means of "protecting" them from danger. Male cats do not recognize their own offspring and do not participate in their care. Males are threats to the young and many females protect their litter against any perceived threat. Intact male cats, in particular, may pose real threats. Male cats commonly kill young kittens.
As a general rule it is advisable to have a cat neutered, also called spayed (for females) and castrated (for males). Not only does it aid in control of unwanted kittens, but also it greatly minimizes the risk of problems associated with the reproductive tract and behavioural problems associated with sexually intact animals.

The history of the cat itself:
"A cat is a cat is a cat," wrote E.E. Cummings. And history would seem to agree with this distinguished poet. Maicis, the primitive ancestor of cats, was a small, tree-living creature of the late Eocene period, some 45 to 50 million years ago. According to earliest records, the first sign of domestication of the cat (Felis silvestris catus) dates back 8,000 years ago where bones of cats, mice, and humans were found buried together on the island of Cyprus. The family of cat can trace their genealogy back to ancient Cyprus and Egypt.
Growing crops became a way of life for Egyptians. Since crops could only be harvested once or twice a year, the question became how to store the life-giving grains? Enter rats, mice and other vermin who quickly adapted to human ways for the promise of a free meal. Just as grain stores attracted rodents, however, so rodents attracted cats. Along with rats and mice, the cobra and two kinds of vipers represented dangers to the human population. And while people were almost helpless to defend themselves against these, cats were not. Along came Felis silvestris libyca, the Libyan subspecies of the wild cat. It was larger than our domestic cat. Some believe cats were brought into Egypt from Nubia during the New Kingdom. Others place their origins with Felis silvestris ornata and believe they were brought from Persia circa 2000 BCE. But these are minority opinions.
The farmers wanted to encourage cats to stay around the house and farm so they left milk soaked bread, fish-heads, chicken wings and other scraps of food to attract cats and probably started to 'friendly scratch' them. Cats simply discovered an ecological niche for themselves, a steady source of food, and affection from their human company. To overcome the natural fear that wild cats had of humans, they were most likely also captured as kittens and hand-reared.
However, the relationship between Egyptians and cats was unique. During that period of time, Egyptians owned all kinds of animals including cattle, sheep, fowl, pigs, dogs and monkeys. Cats freely roamed the land and came and went at will. Over time, felines with less solitary dispositions went indoors to chase, eat, cuddle and sleep…
Laws were created at that time to protect cats, since they were held in such high regard. The ancient Egyptians developed cat cults and worshipped a cat-headed goddess named Bast or Bastet. Bastet had the body of a woman and the head of a cat. Associated with fertility, motherhood, grace, and beauty, Bastet's largest temple was in the city of Bubastis. Not only did they mummify thousands of cats, they even mummified mice, presumably to feed their mummified cats in the afterlife. The word for cat in ancient Egypt was "mau," similar to our "meow," a universal cat word. About 4,000 years ago, the ancient Egyptians carved wooden figures of cats. They also made furniture and jewellery in the shape of cats. From about 332 B.C. to 30 B.C., animals began to be raised for the specific purpose of being turned into mummies. The mummies were sold to people on their way to worship a god and left at the temple as offerings. Scientists have uncovered a gruesome fact: many cats died quite premature and unnatural deaths. Two- to four-month-old kittens seemed to have been sacrificed in huge numbers. So many cat mummies were made that researchers can only guess that there were millions of them. (For more information about religion, myths in combination with cats look under 'myths, legends and ritual use'.)

Cats were so good at catching rodents they soon found their way aboard barges on the Nile River as mouse catchers and companions to captains and sailors. Cats soon sailed aboard ships to countries bordering the Mediterranean including Greece and Italy. Overland caravans lengthen the cat's popularity to the north and east. Slowly cats migrated to India, China, and Japan, where they were highly prized as pets and impressive rodent killers.
Cats lived with soldiers in trenches, where they killed mice during World War I. About 37% of American homes today have at least 1 cat.

Anatomy/ Fysiology:
Cats have five toes on each front paw, but only four toes on each back paw. Cats lack a true collarbone. They can generally squeeze their bodies through any space that they can get their heads through. A cat has more bones than a human; humans have 206, but the cat has 230 (some cites list 245 bones, and state that bones may fuse together as the cat ages). Almost 10% of a cat's bones are in its tail, and the tail is used to maintain balance. The domestic cat is the only species able to hold its tail vertically while walking.
Cats' hearing is much more sensitive than humans and dogs. Cats have 32 muscles that control the outer ear (compared to human's 6 muscles each). A cat can rotate its ears independently 180 degrees, and can turn in the direction of sound 10 times faster than those of the best watchdog. It may take as long as 2 weeks for a kitten to be able to hear well. Cats respond better to women than to men, probably due to the fact that women's voices have a higher pitch.
In relation to their body size, cats have the largest eyes of any mammal. A cat sees about 6 times better than a human at night, and needs 1/6 the amount of light that a human does - it has a layer of extra reflecting cells which absorb light. Recent studies have shown that cats can see blue and green. There is disagreement as to whether they can see red. Kitten's eyes usually open between 7 and 10 days, but sometimes it happens in as little as 2 days.
A cat has approximately 60 to 80 million olfactory cells (a human has between 5 and 20 million).
Cats have a special scent organ located in the roof of their mouth, called the Jacobson's organ. It analyzes smells - and is the reason why you will sometimes see your cat "sneer" when they encounter a strong odour.
They have true fur with an undercoat and outercoat. Most cats have no eyelashes. A cat has a total of 24 whiskers, 4 rows of whiskers on each side. The upper two rows can move independently of the bottom two rows. A cat uses its whiskers for measuring distances.
A cat's brain is more similar to a man's brain than that of a dog. Both humans and cats have identical regions in the brain responsible for emotion.
Cats have AB blood groups just like people.
Cats lose almost as much fluid in the saliva while grooming themselves as they do through urination.
Many cats cannot properly digest cow's milk. Milk and milk products give them diarrhoea.
Cats are prone to many of the same problems that people are. Cancer (also leukaemia), kidney disease, heart disease, and dental disease are not uncommon and they can have a form of aids. Well-known to every cat owner are of course the ear mites or fleas and several species of intestinal worms that can infest cats and rob them of precious nutrients.
Cat's urine glows under a black light.
Cats may live fifteen or more years.

There is one aspect of cats that is truly unique -- their dietary needs. Cats, unlike dogs or people, are obligate carnivores. In other words, cats must eat animal tissue to maintain their long-term wellbeing.
From the muscle of its prey, the cat obtains protein. And from the bones and viscera (intestines and other organs), it obtains vitamins, minerals, and other important nutrients. The cat also meets most of its fluid requirements through its prey.
It eats ten-plus small meals in a 24-hour period. The cat's tendency to eat small but frequent meals has determined how it processes food, which in turn, affects its dietary needs. Thanks to plentiful food in the wild and its frequent dining habits, the cat has developed a metabolism that is significantly different from that of most other mammals. The cat relies on its diet to supply it with certain substances (such as taurine and arginine) and to meet its higher-than-average protein requirement. From the cat's point of view, what is the sense in wasting energy synthesizing certain substances or conserving protein within its body when a steady diet of prey can readily supply those substances?

Taurine, a sulphur amino acid derivative found in meat and other animal foods (except for milk and milk products of other mammals - but, as earlier stated, taurine is found in cat's milk!), appears to shield the heart from harm. It's best known for empowering bile acids to clear cholesterol from the body. It may also fight cellular troublemakers that can damage the heart. Studies in animals suggest that taurine lowers blood pressure as well - yet another heart-healthy property. Although research has produced conflicting results, taurine may also benefit vision disorders, epilepsy, and gallstones. Taurine is an essential dietary nutrient for cats because the rate of synthesis under most conditions is less than the rate of loss from the body. Cats are unable to use the strategy of many other mammals of switching to the glycine conjugation and conserving taurine when dietary taurine becomes scarce. Also, the loss of taurine from the body is dependent on the composition of the diet and the method by which the diet is processed. Taurine deficiency in cats causes reproductive problems, blindness, and heart disease. Furthermore, a number of studies have shown that inappropriate taurine levels can adversely affect immune responsiveness. Studies have shown, that there are changes in the host defence mechanisms in cats fed diets deficient in taurine. These host-defence mechanisms are present to protect individuals against infections with pathogenic organisms (bacteria, viruses, parasites) and against the development and spread of malignant tumours. Histological changes in the spleens of taurine-depleted cats were consistent with depletion of B-cells and T-cells and follicular centre reticular cells. Lung lavage fluid from cats fed taurine-deficient diets also contained a reduced proportion of neutrophiles and macrophages that produced increased quantities of reactive oxygen intermediates associated with lower Taurine concentrations. Taurine deficiency has also a profound adverse effect on feline pregnancy and outcome of the progeny. Such females have difficulties in maintaining their pregnancies, frequently aborting their foetuses. Pregnancies which do reach term frequently result in stillborn and low-birth-weight kittens. Survivors have abnormally slow growth rates and exhibit a variety of neurological symptoms. Abnormal hind-limb development and thoracic kyphosis may happen.

Arginine is another essential amino acid. An arginine-deficient diet leads to a situation in which the cat develops toxicosis because it can't adequately convert the harmful waste product ammonia into urea (normally eliminated via the urinary system). An unusual characteristic of cats is that they cannot form vitamin A from beta-carotene. Cats are also inefficient at converting the amino acid trypophan into the vitamin niacin. A cat might survive a loss of up to 50 percent of its overall weight. But if it loses just 15 percent of its water weight, it will die.
Studies of cats' eating behaviour have revealed that several factors -- such as how a food smells, how it tastes, how it feels, and how warm it is -- influence what a cat will or will not eat. In terms of flavour, cats prefer salty, sour, or bitter-tasting substances. Most cats adore sardines. We also know that cats don't develop a sweet tooth because they have no perception of simple sugars.
Eating grass often occurs when the cat needs to clean out its stomach by vomiting (probably to get rid of fur balls). If your cat does not have access to grass, your cat will use houseplants or anything similar. Vomiting will occur soon after the cat has eaten grass. It has been said that cats eat grass to obtain folic acid, something that cats need in minute quantities for its wellbeing. Folic acid cannot be obtained from meat.

Wherever they went, they made perfect pets for at least some of the people they found. But they never entirely lost their ancient, independent edge. As Henry David Thoreau noted, "the most domestic cat, which has lain on a rug all her days, appears quite at home in the woods, and, by her sly and stealthy behaviour, proves herself more native there than the regular inhabitants." Joyce Carol Oates puts it this way: "The wildcat is the real cat, the soul of the domestic cat; unknowable to human beings, yet he exists inside our household pets, who have long ago seduced us with their seemingly civilized ways." Makes you wonder who keeps whom.
Kittens learn social skills from the mother cat - how to get along with each other, as well as how to interact with humans. Generally speaking (except for kittens born to a feral mother), kittens that have remained with the mother cat longer will make more sociable pets.
They have various personalities. Some are solitary individuals while others are more gregarious. Traits associated with cats include cleverness, unpredictability, healing and Witchcraft, since in ancient times it was believed that Witches took the form of their cats at night. It was largely in the Middle Ages that the black cat became affiliated with evil. Because cats are nocturnal and roam at night, they were believed to be supernatural servants of Witches, or even Witches themselves. Partly because of the cat's sleek movements and eyes that 'glow' at night, they became the embodiment of darkness, mystery, and evil, possessing frightening powers. (To read more about this see the section 'myths' etc.)
Purring does not always indicate that a cat is happy and healthy - some cats will purr loudly when they are terrified or in pain. Cats purr at the same frequency as an idling diesel engine, about 26 cycles per second. At two to three days old a kitten will start to purr, the purr is very quiet and can be difficult for a human to hear. As the kitten grows the purr gets louder. A kitten purring is a signal to the mother that all is well and the kitten is contented and getting enough food when suckling.
Cats normally greet each other by rubbing faces. When a cat greets you by standing on its hind legs, it is simply trying to reach your face. If you were to lower yourself so your face is within reach, your cat will rub their face with yours. This is only done to humans that the cat trusts.
Cats have scent glands on the temples, around the mouth and at the base of the tail. When a cat rubs itself against you, it is rubbing off some of its scent to say: "this is mine". Only other cats can smell this scent.
Kneading is when a cat extends and retracts its claws, usually when it is resting on its owner's lap. This behaviour comes from kittenhood, kittens knead their mother while suckling to make the milk flow more freely. Adult cats will do this when they feel safe and contented. They see their owners as surrogate mothers and, as pampered pets, will retain some kitten characteristics through their adult life. If the cat dribbles or sucking of the owner's clothes happens whilst kneading, the cat in question will probably have been taken from its mother too early and never had a chance to grow out of the behaviour naturally. These behaviours are usually for life.
If a cat is frightened, the hair stands up fairly evenly all over the body; when the cat threatens or is ready to attack, the hair stands up only in a narrow band along the spine and tail.
A cat will spend nearly 30% of her life grooming herself.
When a domestic cat goes after mice, about 1 pounce in 3 results in a catch. A cat can jump 5 times as high as it is tall.
Mature cats with no health problems are in deep sleep 15 percent of their lives. They are in light sleep 50 percent of the time. That leaves just 35 percent awake time, or roughly 6-8 hours a day. Cats come back to full alertness faster than any other creature.
A wagging tail could mean the cat is angry or can mean that the cat is feeling indecisive - it wants to do two things at once and cannot make up its mind which action to take.
A cat needs to sharpen its claws by stripping off the old shell to reveal a new one. Scratching at furniture is one way a cat will renew its claws. It is also a way for the cat to exercise its claws and paws, and for scent marking (there are scent glands under its front paws).
Flehmening is when a cat screws up its face, the lips curl back baring its upper and lower teeth allowing more chemical aromas to register in the Jackobsen's Organ. The Jackobsen's Organ is situated in the roof of the mouth in two sacs. In wild cats it helps with the 'navigation' of the area and the nearby animals. This organ is also connected to the part of the cat's brain concerned with sexual behaviour and appetite.
Owners of outdoor cats will eventually be presented with gifts of dead creatures, such as mice and birds. For the cat, this is perfectly natural - this behaviour should never be punished in any way.
A subordinate cat will bury its faeces so as not to demonstrate its presence to more dominant cats. A dominant cat will leave its faeces uncovered. A cat kept on their own will bury its faeces by scratching on the litter tray, this has nothing to do with cleanliness - it is a sign that the cat feels that its owner is dominant. In households with more than one cat, you will often find that one or two cats leave their faeces uncovered, whereas the rest will cover it up.

More cats on the catwalk:
Catwoman is one of Gotham City's most prominent villains. She has the appearance and grace of the animal from which she gets her name. Indeed, at times she has been known to meow, and when Batman is close by her voice takes on a distinctive purr. Throughout the day she will take time out for a cat nap and she has a fondness for milk. She also is allergic to dogwood
It is easy to see that Catwoman is attracted to Batman in a strong physical way. The fact they are on opposite sides of the law will undoubtedly keep them apart. Though she is attracted to Batman, she has the sense to realize he is a hinderance in her plans.
