Despite looking cute and fluffy, cats can be murderous killing machines to wildlife around a neighborhood. Nancy Brennan, a bird-watcher, moved in with George the cat and his owner, who would become Brennan’s husband. As a bird lover, Nancy was appalled at George’s habit of killing birds.

Nancy first tried to put bells on George’s collar but when that didn’t work, she discovered that birds have keen eyesight so she created a colorful collar to make cats more visible to birds. Amazingly, it worked and didn’t seem to affect George’s enjoyment of the great outdoors.

So if your cat kills too many birds, try making it more obvious with the Birdsbesafe cat collar. To learn more about this unique collar, click here.
