Poor Merlin, I feel so sorry for him. What a place to be if you don't have your fur coat.
I wish I could help you but I have no idea how to knit or sew. I guess the next best thing is to pile the blankets on. I'll be he does make quick potty trips right now. How about something warm to drink, but not sure what that could be. Be sure to give Merlin some hug from Perry, Daisy and me
