Thanks FaeryBee, like I said we have only had him one day and I would be devastated if anything permanent has happened. He is such a calm and trusting little thing, he does seem very relaxed when we hold him and I think this is a good way to keep him warm. I just want to be sure we are doing the right things for him in the interim.
I will let you know how we go at the vet tomorrow. Thanks for your well wishes
