Hi, I have just adopted 2 piggies from a rescue, and they are beautiful. I have never kept piggies before, so I am learning as I go along. I would like to buy them a snuggle sac/fleece, as they are great for cuddling them in (especially if the children are holding them). I wondered whether I should buy a double bag for them to sleep in at night, or 2 singles? What are your thoughts? Thanks Jane
