I am grateful for cat trees because they make my cat VERY happy! He enjoys climbing from level to level, playing with the dangling mouse, peeking out from behind its posts and (most importantly) scratching on it! This keeps my new furniture scratch free. It’s also tall enough that on the top-most tier, my cat is eye-to-eye with me. He seems to really enjoy that, patting me on the top of the head with his paw. Oh! I also like the color of it – ‘just seems to match with color scheme of the house.
