Pet cats kill lots and lots of birds. If you want to help preserve bird species, you can do one of two things. You can keep your cat indoors, or you can make your cat more visible to birds.

I keep my cats indoors. It is safer for them, and they can’t kill the native wildlife.

I don’t have any affiliation with Birdsbesafe. I think it is a really great idea, and hope it will catch on.

“The conservation implications are clear: if owners of outdoor cats choose to use Birdsbesafe® collar covers, a significant factor in the decline of bird populations would drop precipitously.”
