BREEDING EXTREME TRAITS IN CATS
By Dr. Michael W. Fox
I expressed public concern forty years ago that some breeders of cats would start to selectively breed certain varieties whose physical structure and genetics would mean a life of suffering and costly veterinary treatments as had already happened with many breeds of dogs selected for extreme traits.
The baby-like and for some, comical appearance of brachycephalic (flat-faced or ‘peke face’) Persian and Exotic shorthair cats is of especial concern. This extreme facial deformity is associated with many health and welfare problems including: tear staining and eye problems; respiratory difficulties and associated inactivity; misalignment of the jaws with dental and oral problems; deformation of the skill leading to difficulties giving birth and later development of hydrocephalus, reduced brain space and herniation of the brain into the base of the skull with serous neurological and painful consequences. The Scottish fold cat with deformed ears often has severe osteoarthritis. Cats with various degrees of dwarfism with shortened and deformed legs have difficulty ambulating and engaging in normal behaviors. No matter how appealing these “Munchkins” may seem, their deliberate propagation with inherited handicaps is surely unethical.
The worst deformities, in the opinion of several veterinarians, are those of the so-called Bullycat, bred in America by cross-breeding hairless Sphynx cats, that suffer from skin issues, cold and sunburn easily, and short-limbed, indeed crippled, Munchkin cats. The combination of these genetic abnormalities in the Bullycat mean a life of suffering and limited physical ability.
So cat fanciers please wake up and be more caring and responsible and prospective cat owners adopt only from your local shelter and don’t support such inhumanity by purchasing a purebred cat with such extreme abnormalities, no matter how appealing they may seem to you.
More Depraved Cat Breeding.
Now we have two new abnormalities that are being selectively bred by some cat fanciers playing demi-god with their genetics that I consider depraved. Cats need their tails as a mode of communication, expression of emotion and intention, and for territorial and in-home spatial marking. These breeders are going after cats’ tails and deforming them.
Sphinx tail impedes cats’ ability to communicate.
Cats bred to have tails that curl up and over their back might not communicate well with other cats at first, but with time, they may learn to use other communication cues such as facial expression, body language, ear position and odors, according to a study in the Veterinary Journal. A tail held straight up signals contentment, but so-called American ringtail cats cannot hold their tails up, reducing some communication ability. See Morgane J.R. et al.
