Droppings actually consist of three recognizable parts: feces, clear urine and a white urine called urates. Generally, the feces part of the dropping should be green or brown. It should be solid and coiled like a snake, segmented or in pieces. The urine portion of the stool should be clear and watery. Urates should be an opaque white-beige crystalline material. Sometimes the urine and urates are mixed, creating a cloudy-looking material, but usually they are separate.
Looks fine to me,Having four greys i get a mixture of poop ! but sometimes they will do a bigger poop during the day.Just keep an eye on him & be on poop control for a few days, as long as he isnt showing any other symptons,i think you have nothing to be worried about
