I have an outside cat and I wanted something that was off the ground that would keep her warm while she was in the garage at night. This is great! She loves being on the top if it's warmer and when the nights are colder she can move to the Sherpa.  She isn't too interested in the little toy, but, being an outdoor cat she has other things to keep her busy. This is well made Easy to assemble and I can wash it! I love that.    

Pros: Easy assembly
