To make dumps: Preheat the oven to 180ºC . Mix together the dump ingredients in a large bowl. Mold pieces of this mixture into various size/shape dumps.
Place so they don't touch each other in an ungreased baking pan. Use an extra pan if they don't all fit. Bake for about 20minutes or until they are all brown, firm and slightly crusty. When done transfer to paper towels to drain.
Meanwhile, put all four litter ingredients into a largesaucepan. Heat on high until the water comes toa boil. Stir, turn heat to low and cover the pan. Simmer without liftingthe cover for about 14 min.
Spoon the rice and dumps into the now empty baking pan, leaving some dumpspartially uncovered, the way a cat does when he/she is in a hurry. Serves8-10 litterbox lovers.
