"Between my boyfriend & I, we have 5 cats ... My cats have had "safety" collars their entire lives, but when one of his cat got her old collar stuck on a drawer handle, I'd decided we needed to do something right away. I ordered five collars (replacing my cats too), in four colors and we were pleased with all of them. In fact, his other cat has never kept a collar on, but has yet to remove her new one. It is light and doesn't irriate her. Now the only problem we have is the bells ringing as they chase each other at 2:00 AM ... :-)"
