This is exactly what I wanted, and although my cats are too large for the hammocks, everything else is sturdy enough for 2 cats, (mine are 13lbs. and 16lbs.). I use the cage outside under the eaves of my garage next to their favourite tree all summer long where it's shady and cool. They'll spend a couple hours at a time outside watching and chatting it up with the squirrels and birds. In the fall I take it to the basement and clean and inspect all the parts. I'm giving it 5 stars!
