I'm not sure how I feel about this cat tree. I put it together and it is bigger than I imagined but a very nice, sturdy tree. I have 2 cats and bought it for the Tuxedo. She came in and investigated, decided she liked it, curled up and went to sleep. Then the next day she was sick. There is nothing else different for her except the cat tree. I'm fine, my other cat is fine(she didn't sleep on the tree but investigated it). I removed the tree from the house, put the old one back in place and googled a lot. I think the problem may be formaldehyde fumes. My cat got better in 2-3 days. I didn't notice an odor but my cat was clearly sick - not eating, not active, sleeping. I haven't decided whether to air the tree out and try again or not. Anyway, my sensitive cat had an issue with this Made in China tree.
