This is a very nice jungle gym for my little seventh month old energetic Spider-Man kitty! I adopted Ocean last summer and he is quickly getting longer, taller and stronger everyday and needed something larger to play on. It is sturdy and very well made with a nice safety strap. The blue is super soft! He loves to climb all over it, use the scratchers, play with the balls that jingle, snuggle in the caves, relax on the top beds watching all the animals outside and fall asleep in the sun. It gives him a nice tall view of the trees, lake and the mountains. I also put some of his toys on it. He has lots of fun. Ocean loves his bluewhite castle! Thank you
