I recently adopted 2 kittens. I have had them about 7 months now and they each use the litter box about 4-5 times per day. I am dumping at least 7-8 poops and a gallon of clumped pee every day. I'm not sure if they are supposed to poop that much or am I feeding them the wrong food. I give them each 1/2 cup of dry food in the am and 1/2 cup of dry mixed with wet each night. Please let me know what I can do to remedy this situation. Thanks.
