For information on local licensing and neutering laws, contact your local health department or humane society. Locate bird feeders in sites that do not provide cover for cats to wait in ambush for birds. To prevent cats from climbing to bird nests, put animal guards around any trees in your yard that may have nesting birds. Don't dispose of unwanted cats by releasing them in rural areas. This practice enlarges rural cat populations and is an inhumane way of dealing with unwanted cats.
Cats suffer in an unfamiliar setting, even if they are good predators.
Contact your local animal welfare organization for help. Eliminate sources of food, such as garbage or outdoor pet food dishes, that attract stray cats. Don't feed stray cats. Feeding strays maintains high densities of cats that kill and compete with native wildlife populations. Cat colonies will form around sources of food and grow to the limits of the food supply.
