Hi guys, I just registered my cat and would like to know what type of collar makes most sense to attach the I.D. tag? If he gets out - what good is a breakaway collar, if it's just found lying on the ground due to a snag, or someone finds him and tries to catch him by the collar? Are cat harnesses ok for long-term use, or is that metal ring that joins the neck/chest piece, very uncomfortable for him? Thanks for any suggestions.
