I've had this set up for a couple of weeks now, love it! I have 3 cats and I bought two, but I have only been able to set up one of them because the only place I had room was the laundry room. We're moving to a new house this summer, so hope to find room somewhere to set up the second one. The only thing is - definitely buy the dome! My cats are incredibly messy and dig, bury and dig some more. So I have a bit of a mess on my laundry room floor. I ordered the dome and am sure that will take care of it.
