Mark, I have replied this in the other forum also, but I said runny but I don't think they were that runny. I was still able to lift them out with a teaspoon and they still kept their shape.
It was still whole on the paper when I spread it out. I have a microscope and could see no visible movement, parasites or and other single celled organisms.
I'd say it was more of a freshly done, wet poo rather than runny. Usually when I get to them they are dried hard bullet types. Must have caught this one after it was just done. But I will keep an eyes out for others.
