Bigger than I had expected but my cat loved it! He went in and played/laid in there comfortably so it made me think I might not use it as a litter box! But in the end I did and I’m so glad I got this because it resolved the issue. I had a normal litter box without any covers and I was annoyed by all the litters scattered around the floor. I see some litter and cats’ hair on the black top cover so it still is a bit messy but less mess which is less stress for me.
