I do remember and I really should have asked about him before now. I have been occupied mentally and physically as I recently accepted and rehomed a pair of budgies that have some health issues and have been teaching the new owners how to take care of them and then a young kitten got inside my fenced yard and my 2 100 pound puppies decided to play with it, so it has been touch and go as to whether it was going to survive. I am now sure that it is going to recover although it will be delicate for a while longer.
I am glad that you finally are having some success with Charlie and I do apologise for not asking about him, my bad. I would love to hear more about how you and Charlie are doing.
