morgan has an xs coach collar as well and the only way to get it stuck in the mouth is if its too loose. she is 4.5lbs and should be wearing an xxs collar but it works because she doesn't mess with it. those collars don't stretch or give, so there is no other way she'd be able to get it in her mouth.
to get her used to a collar i'd get a cat breakaway collar to start off with. make sure you can only get one finger underneath it when its on so she can't get it in her mouth. and make sure you are with her when she has it on.
