Teacup (Dwarf) Cats Another "dwarf" cat, also known as the "teacup cat", is a cat born with one of a number of mutations that cause the cat to be proportionally small rather than just short-legged. Although no single gene is involved and the cause of the dwarfism may be harmful to health, "teacup" cats have increased dramatically in popularity. Guinness World Records has a category for "Smallest Cat" which may contribute to the desire to breed ever-smaller cats from cats with potential genetic and health issues. "Teacup" cats cause controversy in the cat fancy with many breeders considering them scams. Some may be runts born too early, or have nutritional deficits during kittenhood leading to retarded growth. When buying "teacups" of any animal it is necessary to exercise caution as primordial dwarf cats may have a number of health problems[9]. Undersized cats also result from mutations such as types of mucopolysaccharides or other metabolic disorders. As there are many different genes that retard growth, and as small stature may be due to non-genetic causes or to "teacup" cats coming from kitten mills, it is unsafe to generalise on health issues. Less scrupulous breeders may mistake serious metabolic disoprders as dwarfism. While some "teacup" cats do not show health problems, the health problems that have been reported in others include: Severe growth retardation causing bones to become misshapen and soft. Slowing rate of muscle mass growth. Causing weakness and a possibility of decreased use of limbs. Heart murmurs and enlarged heart. Seizures and other neurological problems, possibly causing blindness. Soft spot in top of skull, leaving cat susceptible to major head trauma. Misshapen jaw and bowed legs. Shortened lifespans Undeveloped or malformed reproductive organs Dwarf cats are domestic cat breeds which have the condition of dwarfism due to a genetic mutation. The Munchkin is the founding breed of chondrodysplastic (short-legged) dwarf cat. Through outcrossing the Munchkin with a variety of normally proportioned cats a substantial number of dwarf breeds have been developed. The major dwarf breeds as set out on the Dwarf Cat Association's website are as follows: Bambino - A cross between a Munchkin and a Sphynx cat Dwelf - A cross between a Munchkin and an American Curl Napoleon - A cross between a Munchkin and Persian cat Skookum - A cross between the Munchkin and LaPerm cat Kinkalow - A cross between the Munchkin and the American Curl Lambkin - A cross between a Munchkin and Selkirk Rex Genetta - A cross between Munchkin, Bengal cat, Savannah cat , Domestic Short Hair cat and Oriental SH - exotic, spotted/marbled cat like a wild African Genet. Minskin - A cross between Munchkin and Shynx cat, Devon Rex cat and Burmese cat The development of dwarf cats is at a fairly early stage (since the mid 1980s) and dwarf cat breeders are striving for recognition with the major cat registries. They are not widely accepted outside of the USA. They are potentially banned under the European Convention for the Protection of Pet Animals (European legislation) and have been condemned in the British Magazine Cat World. For example, an insight into registration problems can be seen in respect of the Skookum as recited by the founder of this breed Roy Galusha. In addition to chondrodysplastic dwarf cats, there are a number of normally proportioned dwarfed breeds. These are usually termed "mini-" or "teacup" to differentiate them from the short-legged dwarf cats. Some may be due to a condition similar to primordial dwarfism found in humans. There are several lines of Teacup and Toy Persians currently bred, with some due to a spontaneous mutation and others due to consistently selecting and breeding the smallest individuals from each generation to progressively downsize the breed. American Miniature Cats Some breeders come across an unusual situation where a normal sized cat will give birth to unusually small kittens. Others breed small cats, with small cats, to create consistent miniature cats. Many different breeds have been used to create the American Miniature. Some of the breed influences are Manx, Siamese, Persians, Polydactyls, and various others including crossbreeds. Size is really the determining factor in American Miniatures. The American Miniature is approximately half the size of the average housecat. Weights will vary but should never exceed seven pounds at maturity. Height and length are a more accurate way to determine if a cat is a true miniature. American Miniatures are not dwarfs. They are perfectly proportioned, only in a smaller size. Miniature cats come in all coat colors and color patterns, as well as all hair types. Polydactyl and short-tailed cats are allowed. Personalities can vary depending upon their parentage as can temperament and activity levels. Mature cats of eighteen months or older that measure twelve inches or less, (measuring from the base of the neck to the base of the tail fully stretched out) and measure ten inches or less from the top of the shoulder blade to the top of the paw or "wrist" and are not heavier then seven pounds are considered registerable as miniatures. Miniature kittens typically weigh one hundred grams or less at birth and grow at a slower rate then average. Kittens that exceed one hundred grams at birth are likely to outgrow "Miniature" status. Kittens out of two registered parents qualify for registry. However, for breeding purposes, any cat to exceed the breed standard for height and length should not be bred. Also any cat that is at the top of the breed standard for breeding stock should only be bred to smaller cats then itself. Breeding stock or unregistered outcrosses must not exceed fourteen inches from the base of the neck to the base of the tail, or exceed eleven inches from the shoulder blade to the wrist. Neither can they exceed the seven pound weight limit. American Miniatures have no more health problems then any other cat. Miniature females may have trouble giving birth if they are too small or if they are bred to a significantly larger male. Careful consideration and selection on the breeding pair should be top priority in any breeding program.
