So I received the iris litter box I can say I was pleased by it very simple to remove lid .But I really didn’t think my cats would use it climbing through the top of it so I have an older cat and younger cat so I set it up put litter in it and left it with another one regular box to my surprise my younger cat loves it very big she can move around and no cat litter on my floor absolutely love it and so does my Mia my cat
