While unowned cats do kill birds, they kill proportionally more rodents. Other issues, such as the decline of natural habitat, deforestation of migratory habitats, window collisions and use of pesticides also have a negative impact on bird populations.
Do your part: spay/neuter your cat(s) before they have even one litter, and please don’t let your pet cats roam free outdoors. If you want your cat to have some time outside, make it safe for the cat AND local wildlife by building an outdoor enclosure, installing cat fencing, or taking your cat outside on a leash and enjoying some outdoor time together.
Some organizations are working on initiatives including “Cats Safe at Home” to encourage people to not let their pet cats roam free.
Fewer free-roaming cats mean fewer unowned cats born on our streets. Fewer cats means less predation on wildlife.
