My kittie loves this (& smell gone).
She lives in this thing nearly, she wants to be petted in there, jumps out of it and rushes her prey (toy) from it and it is the most favourite play tunnel she has had.
As previous reviewers have said, it did smell at first, and it didn't go away by itself. But it's a pretty sturdy construction so I put it in the washing machine on Wool wash and the smell went away completely and it dried just fine. Still looks like new. 5* from us.
