No so far so good but underneath the fleece I used a puzzle mat the big foam abc mat and that she tried to chew on so I immediately took it out and just use the fleece now. And she hasn’t even tried to chew it. Yea some rabbits will chew the fleece my daughters bunny is a little older and set in his ways she has no choice But to use carefresh because her rabbit immediately tried to eat the fleece.
