Pet Overpopulation

The vast majority of feral cat caregivers, in the order of 80%, are women who have a unique voice that needs to be heard in the public policy debate on legal protections for animals. In particular, the public needs to know that their definition of protection is rooted in sterilization, not "humane" killing; and, moreover, that they are dedicated to protecting individual animals, and do so at great personal cost. That women have long been marginalized is a historic fact, and that the legal remedies have been incomplete is a present reality.

Can a single female cat and her offspring really produce 420,000 cats over just seven years? This article examines the validity and origin of this commonly cited statistic, concluding that this statistic is likely an urban myth. A lower estimate is provided and substantiated by research by biologist Michael Stoskopf, who documented six kittens per year with a 75% kitten mortality.

This report compiles various estimates of dog and cat populations, focusing on data from the American Association of Pet Product Manufacturers (APPMA). The research provides estimates of 72 million dogs and 82 million cats in U.S. households, with about 60% of all households having dogs and cats.

According to Ohio State University, ideas related to cat overpopulation in Ohio differ between rural and urban dwellers and also between cat owners and non-pet owners. In addition, about one quarter of Ohio households feed free-roaming cats, whether or not they are spayed or neutered.

In the 10 years from 1991-2000, nearly 8,000 feral cats were neutered and reintroduced to their original colonies in Rome. The spay/neuter campaigns brought about a general decrease in cats, but the percentage of cat immigration (due to abandonment and spontaneous arrival) is around 21%. This suggests that spay/neuter efforts without complementary education to prevent abandonment may be a waste of money, time, and energy.

The Tokyo metropolitan government's first survey on cat habitation (conducted in 1998) estimates the cat population to be about 1.2 million in Tokyo. 600,000 of these cats were indoor house cats and the remaining 560,000 were outdoor cats, including 110,00 stray cats.

An Ohio State University survey of Ohio animal shelters found that the number of dogs received has decreased by 16% since 1996, while the number of cats received has increased by 20%. The number of dogs euthanized has decreased by 39%, while the number of cats euthanized increased by 14%.
