I was really excited to get this in the mail and thought my cat would love it. Well needless to say, the reviews were correct about the lack of stability for this cat tree. My cat is 3 years old and the size of an average adult cat and when she gets on the 2nd and 3rd tier, it becomes super wobbly. It's apparent that she is uncomfortable because of that. My cat does enjoy the cubby underneath so it's such a shame she cannot put the entire cat tree to use. This cat tree might be more suitable for kittens but not adult cats.
