With a new puppy and an ever inquisitive 10 year old schnauzer the cat's litter box is a major problem for us. I try to clean it as soon as I let the dogs out of their kennels while they are pottying but it never fails Heidi drags out cat poop. Since Jens is still a puppy I am worried he will start to do or get sick off of Heidi's "treasure hunts". I try to notice if Tortilla has gone to the bathroom and scoop immediately but this is not a good solution. Do the self cleaning litter boxes work? I see fairly poor reviews on them but wonder if anyone has decent luck with them. My husband is about at his wits end with the dog dragging out cat feces!
