We tried the litter kwitter but I decided it was too many cooks in the kitchen lol, considering my 20 month old is being toilet trained and my 3 year old is used to going on her own but the litter kwitter was constantly there. I purchased a covered litter tray and use the Pets at Home wood pellet litter. However, whenever Minoush tries to cover his poo he gets it all over his paws, and today it was even all along the bottom of his hind legs. I wonder if this has anything to do with the type of litter? Also I'm thinking about switching to clumping cat litter thinking it may be more hygienic, but wonder if it does last longer that the non-clumping wood pellets?
