Collar wearer here too. His has a bell because someone likes to sneak into rooms he shouldn't be in by himself and cause havoc! (*sarcastically* Yay for dumpster divers....
his is a cat breakaway collar which stays on better than most people think, and will only fall off when it really needs to. If you want the gingle noise without the bell, you can add metal charms to the collar. Kaji has an ID tag, and a small charm with his initial on it. It's super cute!
