Oriental cat proof
I have 5 oriental cats, 2 siamese, 2 bites and a tonk, they can destroy most things, and their last cat tree lasted less than 6 months, including getting replacement parts from the supplier.
This one is great, they love it. They sleep in it, play with it, throw up on it and it still looks brilliant.
We switched the covered basket and the deep basket round, just because we know they like to sit up high and look out.
