I have just recently bought qty x2 of these for my British shorthair cats and there is plenty of room for them to turn around inside the litter trays, ideal for the larger cat. The only thing is you don't get a choice of colour but never the less a good quality product.
Very nice, looks smart and really deep base! The door flap swings easily and very easy to take the top off for cleaning. The only slight issue I have is that it's not possible to pick the colour.
