I was just about to post that Scratchy did put in an appearance later on last night, but now looking at these photos I'm not so sure.
This little hog is smaller than Tuesday night's earlier hedgehog visitors and is about the right size to be Scratchy. He/she also has some of the markings on the back.
However, unless I'm mistaken, it seems to have a darker snout than Scratchy, and - big giveaway this - wasn't scratching.
Possibly this is Scratchy and the itching problem has resolved itself (the ticks fell off?).
Of course, ALL hedgehogs are welcome, but if this isn't Scratchy, I do hope that she is alright.
