This product is AMAZING! I was so frustrated and sad that my cat was leaving me 'gifts' at the door, but since wearing the collar, she is unsuccessful at catching birds. She doesn't mind wearing it at all. I have two of them in rotation now on breakaway collars with bells. If all outdoor cats wore them, millions of birds could be spared. It's a welcome compromise for cats that insist on going out. I tried to keep my cat in but she destroyed the moldings around my doors she was so desperate to get out, so I gave in after several years. I have to add that she still brings mice home, but no longer birds, which makes me very happy.
