"Bring your rabbit in with a urine sample" says the vet. On occasion when we have been in to the vets, he is able to get a sample by holding the bunny and pushing on the bladder, while someone holds a cup and catches the stream. It does not always work for the vet; and I hesitant to try it home, as I have no idea what the right amount of pressure is.
My rabbits are litter box trained. I am pretty sure abunch of wet sawdust as the sample is not going to be a good idea.
If I leave the bunny in a carrier long enough they will eventially pee, not sure I can wringout a sample from a towel. If it lands on the carrier floor (plastic) the bunny is likely to get all wet with little left to pour into a container. I am also not keen on the psychological trauma, this would induce.
Looking for ideas, how to accomplish getting a urine sample from my rabbit.
