Tuesday: there are a couple reasons they sya dogs do that..one is a mineral deficancy (she on a one a day vitamin?) another they say is because it is a learned behvior from watching the mother dogs clean up the den (or whelping box,lol) and yet another is that when dogs are in the wild,they will alot of times eat theirs and other dogs in their pacts feceses so other animals don't know they are in the area as easily.
I would defianatly scoop everytime kitty goes :)
