Some domestic cats, especially in the northeastern United States, have extra toes on the inner sides of the front feet or of all feet. This oddity, polydactylism, is an inherited dominant trait. Cats with this trait are prized by many owners. Male and Female Cats reproduce so prolifically that there are millions more cats than good homes. Female cats come into heat repeatedly and may become nervous or ill-tempered and lose weight if not permitted to mate.
Males wander restlessly, cry loudly to get out, and spray strong-smelling urine about the premises.
To prevent undesired kittens, females may be spayed after 5 or 6 months of age. Males may be neutered after 8 to 10 months to keep them from spraying or wandering. Both operations must be performed by a veterinarian. Neutered cats may need to have their food intake reduced to keep them from gaining weight.
