Kittens always  need smaller cat trees than adults, as there bones are not fully formed .

We recommend weighted cat trees only or wooden ones.

We use wooden and RHR quality .

CAT TREE KING .

The best advice i can give is buy quality first, as it will cost you alot more in the long run buying cheaper ones, as Siberians are strong heavy built cats.

These trees will last years .

OUR cat tree we use .Siberians love to climb and be up high, so for adults the higher the better.

Zooplus, sometimes have good quality wood trees in, for a good price.
