A few weeks ago a friend of mine gave me a cat tree because she was moving and couldn't take it with her. Well I'm moving this week into a much smaller place. I figured out that I can fit both cat trees but it will be a VERY tight squeeze. This new tree is rather large and I know it's going to be difficult to lug it up three flights of stairs. Corkscrew and Tibby still use the smaller cat tree to sleep and play. I can't decide if I should keep the new cat tree or donate it to the shelter I got Tibby from. All of the cats at the shelter have free run of the house and there is no cat tree there for them to climb and play. So, should I keep the cat tree or donate it?
