Disregard incorrect reviewers!
Other reviewers seem to be missing the point about this collar: since the whole thing is elastic, the clasp doesn't need to be quick release. The collar will stretch to slip off (I have seen it work). To the reviewer who complained the collar showed signs of damage, it is likely the cat's own rear claws from scratching, or brushing against twigs, etc. Since the fabric is soft, it does catch on sharp things but this is an acceptable trade-off for the only collar that seems to stay on safely.
