My boy Terrance has started digging under his fleece liner to sleep under it. In the year I have had him, he has always been on fleece. He never expressed this behavior before this week. When he was housed with Phillip neither of them did this. Terrace is now housed with a four month old kit, Jett. Jett began digging under the liners last week. I'm wondering if I can make them stop doing this? Im going to weigh the corners down with toys and see what happens
