Thanks all - you're just great! We've had to postpone the operation, because I've had a nasty cold (feeling a bit better today) - but now John has got it. We're not going anywhere today!

Fister is now back to normal, he is peeing, pooping, eating and drinking. So no harm done in waiting a bit! We know it's a matter of time before he blocks up again, so we WILL make another appointment. He's been laying between us most of the nights, he's so sweet - and such a good earwarmer. We may go on a vacation soon. We will then put Fister in a catpension connected with a vethospital. We can arrange to have him operated about 3 days before we're back and he'll be in safe hands while we're gone. I'll let you know what happens!
