These are just two of the four squirrels that were tearing around in our garden.
Sadly, the one on the left has lost most of the skin and fur from the top of his head. It was looking very sore from the nose up to between the ears. Possibly had an encounter with next doors cats.
Apologies for the poor quality of the photo, I did try to clean it up a bit. This was taken on my phone, from about fifteen feet away and through the double glazing, hence the reflections.
