I'm looking into " Worlds best cat litter" have read good reviews, would like to keep her on cannned food mostly, what is the best?? & maybe some dry food as well?? what is the best? I'm a little nervous about starting over,I live in a small condo now & the front door goes right outside (MK) never went near the door, I quess I trained her not to, any advice is appreciated!! , THANKS
