Hi,
I have one and neither of my bunnies like it. It tends to collapse. The only thing they have done is chew it, for me has been a complete waste of money. I do have the snuggle bed though in the same material/same range which they love. They lay in it, jump in and out,dig it and chill out, one of my best buys. It has been machine washed several times and dries like new. If I were you I wouldn't waste my money on the snuggle tunnel. I deliberated lots before buying it and really should have taken it back when it wouldn't stand up. :wave:
