I don't like collar cause of all the inherent risks so i use harnesses. or i did until someone took my kitten out of it. it fit him perfectly. i want to get a bell because he likes to walk around you legs when you walk and he almost always manages to try and get out the way, right about where my foot goes as i try not to fall. my roommate's cat has one and it is nice knowing where she is. however, jake doesn't want me to get a bell. he hates the bell on mama kitty(roommates cat). he is bright orange, but that doesn't tell me nothin if its dark or the lights are out. i have had pets get their collars stuck until me or my sister helped them. my sister's dog has a collar that we use when we take her places but none of their cats do. Had and Sadie harness would work on because they pretty much just stay around the house but stripes hasn't been fixed yet so he roams and gets in fights and it would probably end up getting him seriously hurt.
