I have to agree that the litter box seems a bit small. I use a Rubbermaid dish pan which has deep sides. At first with only Hopscotch, who weighs 3-4 pounds, a smaller dish pan worked. Well Hopscotch now has a new girlfriend, Mango, who is A New Nealand Red and weighs twice as much as he does. They like to eat their pellets and hay in the litter box at the same time! I got the bigger dishpan and smaller bowls. Since they eat only 1/4 and 1/2 a cup of pellets respectively the bowl does not have to be as big. They always pee in the pan and poop there too! However, if I feed them their salads in theiir basket outside of the litter box they will have the occaisional poo on the rug. I often wonder if I should feed them the veggies in the litter box too as they never have accidents when given their pellets. We like to sit with them when they enjoy the veggies and don’t like talking to them while in the “potty.’
