I read a while ago about the idea of taking a rubbermaid tub and turning it into a extra large litter box. Luna is very picky about a clean litter box and the small one seemed to get too full of waist for her in no time. We moved not too long ago and had quite a few of these boxes left over with nothing in them. So I thought, why not? So today I switched over our cats littlerbox to the new one that I made for them. I cut the interace hole in the top to try to help with scattering litter. They've had no accedents so far and from what I can tell they really like it. Anyone else done this?
