My cats are declawed and I was lucky to find this cat tree that is designed for declawed or elderly cats who can not climb. The design allows them to jump from platform to platform without having to climb and they can still be up high like they prefer. Also this cat tree stated it was made of non toxic material and it certainly is.  I could only detect the slight odor of natural wood and that dissipated quickly. I am also glad it was the soft fleece material and not carpet. It arrived safely with no damage and all the parts and hardware was in the box. So no complaints on this cat tree. 

Pros: Non toxic, no bad odor at all, soft fleece type material, easy to put together, designed for cats that have been declawed or are elderly and can not climb, and has cat scratch post and optional cat scratch rail in case you also have cats with claws.
Cons: None!
