Birdie (my former roommates cat) got a fresh new collar recently

My former roommate's cat started bringing me birds and she now happily accepts her Birdsbesafe collar and has never caught a bird since so I know your collars really work and plus she looks extra adorable.

So far so good

9 days in K is getting back to exploring her neighborhood. Birds building nests now. They are safer when they eat the low hanging berries.

Great product

These collars have helped so much! My cats (the black kitty in particular) were killing birds frequently. I tried bells which only drove my dog crazy but did not save any birds. I got these collars and they have helped probably 85-90%. I also made sure the cats were getting enough meat and water. Many birds have been saved since!! Please make more colors and patters.
They do launder well too.
