My thougths are with you and Bradley. As hard as it is, you know what is best to do, and although he is not responding much to your cuddles, keep giving him love and comfort, I'm sure he feels it and enjoys you being next to him.

If he is ready to go to the RB, I think it's right to let the vet come to your home, so he feels safe.

Love, hugs and comfort to you and Bradley.
