@plesuvius totally worth it! Around here, cats are nearly always kept as indoor critters. They live longer indoors, anyway. Have a window it could reach to sunbathe?
My friend has a litterbox (omega paw, I think) that rolls to sift the mess into a smaller tray so it's easy to empty daily. Alid helps contain the smell in between. (One cat does hate the lid and uses a plain tray). There are lots of variations on that theme.
If you adopt one, please post pictures! :D
