That looks like a normal cecal dropping. They occur about every 9 or 10 droppings, and are usually slimy and more smelly, and can be golden,brown, or black. Sometimes there can be a little foam in them. If you are worried about coccidiosis or worms, you can collect a few fresh morning droppings to have a fecal float performed by your local vet. Valbazen is a good wormer, and Corid is good for treating possible coccidiosis.
