I have a 17 lb orange tabby and 2 newly adopted grey tabby kittens, about 5 lbs each. The tower I previously had did not have enough room for all 3 cats to have a place of their own. The orange tabby would get so upset that his spot was taken and there would be rough housing for the spot. So I was in search of a tower that would suffice all 3 cats. I saw all the great reviews and how most of the buyers had multiple cats and how it would fit large cats. Thank you to all the buyers for submitting their photos. I was sold. I owned 2 cat trees and they were complicated to assembly, but this was so easy. Everyone is happy now except they still fight over for the top bunk ever so often. Thats cats for you, gotta love them. Happy cats, happy life.
