I was looking at license requirements and stuff for the city where I'm going to be living with potential kitty and all cats must carry ID tags. So I was wondering, do cats usually hate collars and try to squirm out of them? Do they get caught on things and potentially choke the cat? Is there any type of collar that's good for cats (like, one that will let them get out if they -do- get stuck)? I want to get kitty microchipped too (don't think it's included with adoption) but I'm pretty sure external tags are required.
