Please help identify this pooh!
 

Since having my grass removed and astro turf put down last week I have noticed this poop running along the edge. What's more, this morning I found a blob of what I can only describe looks like slime next to some (see pics).

I can't work out what animal this is coming from. It looks too small and clustered to be a cat and it's certainly not my dogs!

Any ideas?

Black is Hedgehog if less than an inch or Badger is bigger. The other is Fox.

So from the photos that looks like hedgehog poop to you?

OMG. It's actually worn casts

urghh cannot believe this is happening with astro turf, there supposed to stop them from coming to the surface so looks like I'll be giving them a ring.
