I recently got new bath mats and cut up my old ones to fit Sasquatch's condo. He's been chewing the bath mats and a towel some. Should I be concerned? I don't think he's ingesting any of it. He has other things to chew on-- toys and plenty of hay-- but still occasionally goes for his flooring. He's still pooping normally and everything and seems fine, but just... ehh it makes me nervous seeing pieces of shredded bath mat in his little cage.
