I looked at the picture when I bought this and thought that their was no way a cat could curl up on the top of the platforms that have ladders on them. Also the ladders were going under the platform they were leading too. I was correct. The ladder make the 3 platforms a waste of space. I have 4 cats and only one, who is the only female and was the runt of the litter fits in the hammock, not that she goes in it. She can fit in the caves so goes in there. I thought this would have enough space and be great because as I have said I have 4 cats. WRONG. I should have bought a smaller one and saved my money. The only thing I can say good about it is they were on time. And was as stated. Also the caves aren't solid. There is a piece of fabric with velcro that you work around the circled landing piece. My cats are all around 16 lbs, big cats. I would not recommend this to anyone who has larger cats
