With all the talk about feral cats, it’s a good time to remember that releasing pet cats into the wild to fend for themselves is never an appropriate solution for any problem.
Research by the University of Georgia documented pet cats eating garbage and roadkill and drinking sewer water, particularly young male cats. (See www.kittycams.uga.edu.)
Keeping pet cats indoors protects their health by reducing their chance of injury and parasites. Cats that are “hunters” should be kept indoors to protect wildlife, especially baby birds in the spring.
