Found this dangerous cat as a 4 day old or so kitten in a church's parking lot. Yep and I think his mom abandoned him cause he is pure evil lol. He is so crazy that there is no way to keep him in the house he wants to go out to the yard and hunt. The problem is he hunts everything bunnies, birds, mouse, once I found a mole in my closet. ....so I needed a collar that said look I'm dangerous and now he is in a bright vibrant color with two huge bells on. Does it help? Yes the bigger animals have a chance lol! But the insects and lizards don't. I was concerned about the birds in my yard this has helped a lot. Now the mice in my yard? No chance I have no animals in my yard anymore I'm sure they see him coming. Good quality, fits easy over a collar, beautiful colors. Also if the color falls off I can see where it is now. I need to buy extra so don't buy them all my cat is on the prowl.
