With a little effort, the buckle teeth are easy to pull out, but not too loose.I set this collar as a full refund Reflective Design--Made of high quality nylon material,reflective strap adds more security Adjustable Length--Collar adjustable from 8-inch to 12.6-inch in length,(20-32cm), 3/8-inch width(1cm).No matter whether your cat is fat or thin, it is suitable.
