Thanks again for all the replies. Update: Bertie has had an upset stomach. He has had sickness and runny diahorrea (tmi) I should have responded sooner as he hasn't been able to keep anything down. It has been coming out of both ends. We think that it was something he picked up in the cattery. I took him to the vets and he has kaolin mixture and something else like pepto bismol for cats.Problem is that I have to pretend I'm a mummy cat to give it to him otherwise he claws me to pieces. He is a lot better and has eaten some chicken and drunk some water tonight but still runny tummy. He is such a good boy and uses him tray with very few accidents. The chicken was wolfed down as I only gave him a tiny amount. I have had to wash my fluffy dressing gown as it is the only way I can stop being scratched. Poor Bertie.
