Urine sample help

[LazloTheBunny]

Bit of an update on carlton, he got ultrasound and xrays to check his calcium sludge. He's all clear except still in pain when weeing, he's getting blood work and needs a urine sample. The vets had no luck getting one from him, does anyone have tips for getting samples from super clean and litter trained rabbits. He'll only wee in his and his girlfriends shared litter tray and while it's a big tray he likes to wee where she does. He won't go on puppy pads and will hold it while I have him out in the house. They're litter is sawdust, please does anyone have tips.
The vet have also found he has a bit of gas so they're worried about parasites but as his weeing pain was the original issue they're fully checking that first.

What I always do is clean the litter tray very well and then just put it back in its spot completely empty. If he'll pee in it while it's empty, you can suck it up from the bottom with a syringe. Sending lots of vibes for your boy!

Edit: You'll have to stay close to make sure it's his pee, not his girlfriend's, of course.

A vet ought to be able to express urine from the bladder while they are in the consulting room.

Mine usually have a wee when they are picked up in situations outside their usual patch - often as they are taken out of the carrier and placed on the examination table. Maybe take him eg into the bathroom and leave him in the bath for 10 mins? Keep an eye on him so he doesn't get too stressed trying to jump out. Or leave him in a safe, confined area with a hard floor until the deed is done (a pen in the kitchen, large empty carrier, etc).

Same as above, either pop him in the bathroom for as long as it takes or empty his litter tray and let him go on the base. My vet provided me with plastic beads that mimicked litter so my bunny thought things were normal, except when she peed it just soaked through to the bottom, not sure if your vet can provide something similar.

The beads are a good idea

The vet didn't want to express his bladder as he'd been under anaesthetic and prodded at a lot already, I'm going to try removing their litter tray as they'll sometimes go even if it's not there. I can't really separate him from his girlfriend as he gets anxious and she gets mad when he's away and he was gone a whole day getting x rays and it caused a bit of a fight, he'll also hold his urine a long time.

Thanks, their litter tray is a raised dog bed type thing so it has wholes and a dip in that I'll try and use to catch his wee I guess
