My bun Willow has spent the entirety of her life living in an X-men enclosure on UHaul brown paper and cardboard boxes . The joy of her life is to sit on cardboard and rip it apart . She is now 13yr old and recently was diagnosed with spinal disc issues which temporarily left her unable to use hind legs. I had to redo her enclosure with huge rug remnant with towels over it. This, in addition to pain meds has given her the grip to get up and get around. The reason she never had cloth or rugs in her enclosure when she was younger is that she will eat it. As she is getting better each day I see her starting to eat small pieces out of the towels. I am at a loss . I need flooring that she can grip well but cannot ingest ...suggestions??
