Our girls love their new cat tree! Its super sturdy especially when the little one runs at it full speed to jump to the top perch! The platforms are big enough for our bigger girl (12 lbs) and fun for the little one whos just a year old and loves to play and scratch the sisal. I looked everywhere for a new, 2 perch tree and most of them had a perch and a hammock which I didnt know if theyd like. This is just perfect. I am so happy I found it! Thank you wayfair for once again offering such a great selection of products.
