A side-release breakaway safety buckle has been used to help keep your kitty cat safe, the buckle will open under mild pressure - for this reason this collar is not to be used with a lead. A collar should fit comfortably and safely; you should be able to fit 2 fingers between the collar and your kittens neck - if you can fit more than this, tighten the collar and if you can fit less, loosen it.
