I posted most of the story on behaviour and it can be read here
http://www.catsey.com/showthread.php?t=18277 but they have taken a urine sample which had loads of bacteria in it so it has become health so I added the update here. I don't know for certain what the results are yet as they were very busy with emergencys. So they are going to have a look later or tomorrow morning and call me then. But he is on s/d at the moment anyway to help out as they think he has got something.
I will post more as soon as I know as soon as I know tomorrow. Glad I took him though.
