It doesn’t, no. I accidentally put it on crooked when assembling it and bent it when trying to correct my error to the point that just taking it off was the only logical solution.

This one doesn’t break skin, though. In fact, my cats have accidentally gotten their tail into it several times and reacted with only slight annoyance.

To put it another way: a toddler could stick their head into it and not cry when it hits them, it’s THAT good at stopping gently when it encounters resistance 😁
