I got quick release collars with address tags for both of my cats, as they started going outside before they were microchipped. They've been wearing them for about a year now, but the other night, one cat came home without hers. I assume that she must have got it caught on something, and fortunately, it functioned as it should and released her. I'm wondering whether or not I should replace it now that she's microchipped. I'm not sure whether the potential risks of cats wearing collars outweighs the benefit. Does anyone have any thoughts on this?
