Thanks. We got previous samples on induction. I sent an advice request to the exotics department at Edinburgh and the main thing in the answer was you need to get an uncontaminated urine sample. She suggested either cystocentesis or catheterization. It seems like an impossible task as he urinates on induction of ga and conscious cysto is risky.

IME it can depend on the pig. I've done them before, US guided, with the pig being held uparound its shoulders so it stands on its hindlegs, by an assistant - bladder if full enough tends to flop caudally and ventrally. No clipping, spirit only, orange needle. Only require tiny amount (<1ml). No worse than an injection. If the pig is a wriggler, gas them down as Mr Rowland suggests, then usually still enough (more sedated than GA'd).

I collect on anaesthesia induction. We have a plastic induction chamber and can get enough from that. I'm not a fan of cysts in conscious pigs myself. They tend to struggle and the risk of gut puncture and its consequences put me off Goodluck
