Feline predation is natural instinct. Millions of backyard birds and other
animals are killed by cats each year. Cats are a threat to
fledglings, birds roosting at night and birds while they're on the nest,
at the bird feeder and using a bird bath.

If you are unwilling to eliminate free-roaming cats, do not attract
birds to your yard by putting out bird feeders, bird houses and bird baths.
Eliminating free-roaming cats is the best way you can "protect" your
backyard birds from cat predation.

Responsible pet owners know there is a risk to wild birds. Most local jurisdictions
have enforceable leash laws for dogs, but cats are free roam. Contact your local humane
society if you need help.
