Sibton, my boy improves every day. He is still on a diet of king prawns, chicken broth and milk but I am inclined to think he is just swinging the lead now. He went out today (mainly because I was a bit concerned that he was going to start taking the house down brick by brick - I caught him on the bloody roof last night because I had shut him in the spare room, with bed, food, litter tray etc, but left the velux window open thinking he wouldn't jump that far. Silly me.)
Thank you for asking. I think he is going to be OK. He certainly is getting back to his "normal" ways.
Sorry Carandrog.
