Claims to hold 15 pounds with no issues. My cat is just under that and the crate feels like it's going to fall apart when I put him in it. The plastic is cheap and thin. I used it now to transport my rabbit and smaller cat (6 lbs) and it has already developed some scratching and a crack on one side, one of the plastic clasps for the door broke as well and I think in total I have used it like 10 times.
