The concept is great and I thought perfect for my two kittens. Unfortunately it sheds so much - shag carpet used all over these sections shed little pieces - that I was noticing the kittens were eating the small pieces of fabric and I immediately had to remove it. Maybe older cats won't eat the pieces if I were to offer it to another cat family but I think I might just call it a loss and trash it. Berber carpet would have been a better choice.
