Love this thing. It’s easy to clean and it keeps my dog out of the litter. I have smaller cats (one 5.5lbs and one 10lbs) and they both have plenty of room, but I don’t think this would work for a cat much bigger. The only reason it’s not 5 stars is because the top will eventually unlock. It’s easy to put back together, but I wish there was a better locking system to prevent it from getting knocked off.
