There have been several scientific studies (done independently of BirdsBeSafe) that have proven the BirdsBeSafe collar effectiveness in reducing bird predation. In 2015, a United States-based scientific showed that BirdsBeSafe cat collar covers reduce the number of birds caught by 87% annually. This level of effectiveness means that almost all, but not quite all, birds will be protected from your cat's hunting.
Birdsbesafe collar covers' bright colors simply, but effectively, give most songbirds enough time to notice the cat and fly away. Songbirds have unique eye anatomy that makes bright colors appear extra-bright, even in low light such as at dawn. Birds may see the cat wearing Birdsbesafe's colors from a distance, and gain enough time to fly to safety.
Yes, you will need to have and use a breakaway cat collar to fasten the tube-shaped Birdsbesafe collar cover onto your cat. Breakaway buckles release under pressure, for your cat's safety. Both the Birdsbesafe unit and collar will release at the same time and fall off the cat.
Cats can eat, drink, and sleep comfortably while wearing Birdsbesafe cat collar covers. Because of how it flares out away from the cat's neck, it's not bulky or heavy or in the cat's way. Your cat can wear it all the time (many do!) or only when the cat goes outdoors.
Cats wearing Birdsbesafe collar covers can hunt mammals "normally." Rodents don't have the same eye features that the songbirds do. Expect the usual number of mice and other mammals to be caught.
This expectation is backed up by customer experience and the two science studies.
A scientific study in Australia showed some protection for lizards when cats wore Birdsbesafe cat collar covers. It is postulated that the lizards have color vision abilities that draw their attention to the cat's Birdsbesafe collar cover.
There are three components for success:
Note: Fledglings just out of the nest may, for instance, not be able to fly away from any predator. For a few days when they are learning to fly, fledglings spend more than the usual amount of time on the ground. During times of the year when you notice fledglings in your yard, please contain your cat indoors.
