Rabbits are known to eat all kinds of things that they are encounter and one of these things is fabric, found either loose or as part of furniture.
So is it safe for rabbits to eat fabric at all?
Yes it is safe. Many owners lay down towelling for their rabbits to lie on and keep them comfortable and they will nibble on it because that’s what rabbits do. A little nibbling is fine but just make sure that your rabbit is not consuming it. They should just lie on it and stop nibbling it after a while.
So just watch them with care.
