Hi Baldwin hedgehog
I think, although they can get green poo if they have worms, they can also get it for other reasons, i.e. digestive problems. For instance Pat Morris in his book ‘Hedgehogs’ referred to hogs getting green droppings when they had been drinking milk. I seem to remember being told that it could also happen if they are stressed. But, as Penny says, if it is for several days in a row, maybe it is more likely to be due to worms?
I wonder if hedgehogs would eat wild garlic? Apparently dogs sometimes seek it out – thought to be self medicating.
