Jacob waking up with cats, birds and goats climbing all over him because he’s an high perch =P
Oh gosh. He’d have to be super careful not to upset any perches as he got up. There would be so much indignant bleating and meowing as he moved, but hopefully whatever climbed on him would find a quick way down.
He’s a huge source of warmth, though, so I bet this is most likely to happen in winter or after it rains. He is the best shelter!
