I think Hedgehog but it seems a lot more than i get left me in one go so maybe its a fox

You haven't said if you live in town or a rural invironment but as it was near your rabbits, I would guess at a mink or stoat.

In my experience of poo (which I hasten to add is limited) I think fox's is black and disgusting. I found some like this on our front doorstep and I thought it might be a bird.

I live in a rural (ish) area. Can't say I've heard of any stoat around, but it's probably the best one. I have ferrets but I know it's not theirs
