Does it look like she pulled fur? She will have patches of skin were she pulled fur, I would think they are outside if she has pulled fur and made a nest for them outside
Have hay on hand and when your bun try’s to nibble your clothes put the hay in front of it, I have found that works well and they chew on the hay instead of your clothes accidentally pinching you
The collars are from Meijer, I got the dog collar sized toy and then made it as small as it could go. Very pretty although they do have bones one them😁
I have a pregnant bunny and she only occasionally uses the litter box to pee in, she was fully litter trained before and a second litter box didn’t solve the problem. that might not help
