How Cats Impact Birds
Feral and roaming cats are the leading human-related cause of bird deaths across the globe.
In fact, all of the other causes of bird deaths, such as building glass, poisons, and do not come close to the mortality rate attributed to cats.
There’s no question: cats are lovable companions and efficient hunters. But when left unsupervised, they can be harmful to birds and other populations.

To promote a safer environment for birds and cats, we’d recommend these best practices:
- Keep cats indoors. If they need to go out, ensure they are supervised or on cat patios.
- Spay or neuter cats to mitigate over-populating and stray cats.
- Ensure birdfeeders are high enough that cats can’t easily reach them.
- Support local shelters that rehome stray or wild cats.
