Trap, neuter, return programs make feral-cat problem worse
Feral cats are maintained in the wild by a dangerous, cruel, and illegal practice called trap, neuter and return. After these unfortunate animals are re-abandoned, they are regularly fed, which draws more feral cats and encourages more re-abandonment.
One intact male can impregnate dozens of females, so trying to reduce cat populations by TNR is like, well, herding cats.
It's dangerous because feral cats are reservoirs for disease. Three studies reveal that 62 percent to 80 percent carry toxoplasmosis. Feral cats are now the most common domestic rabies vector. In Florida, where rabid cats attack people, the state Department of Health warns that TNR "is not tenable on public health grounds because of the persistent threat posed to communities from injury and disease." A TNR colony at Point Pleasant Beach, N.J., was removed because rabid cats were biting children.
It's cruel because feral cats lack vet care and suffer from injuries and the same diseases they spread. They infect lynx, bobcats and endangered Florida panthers with feline leukemia, distemper and an AIDS-like immune-deficiency disease.
