Oh Tasher I am SO sorry, I'll go and have a look at your thread now.
My news is much better. Mint (who has a run set up in the kitchen, with his carrying box, litter tray etc) has JUST done his first poo. He would not eat a thing at the vet, and had not pooed, but they said to bring him home anyway. They knew that I would monitor him very carefully. They gave me some fibreplex if I wanted to use it, and he had been given a long acting pain relief. They thought he was stressed and unhappy and would be more likely to eat at home. I took a bowl of our garden grass with me when I went to pick him up, and he ate it immediately. He has eaten ravenously this last hour !
