My bunny is 5 yrs old. For the past 4 1/2 years she has always peed in her litter tray. Lately she started peeing else where in her cage. She is an inside rabbit and spends her time in a large pen with a towel underneith. (the towel is there as it is a cork floor and she slips when she walks on it)

She has started peeing in little spots around her pen, some in the litter box (which we change daily) and some on different parts of the towel.

Originally we thought she may have a urinary tract infection, the vet agreed this was most likely it and we gave her a course of antibiotics. After a short time we began to notice it alot and we did another dose of antibiotics.

I have taken her to the vet again and they said she is just getting lazy. I dont know what to do. Please help

(She has not been desexed)

Rabbits don't just "get lazy". Probably the vet said that because they cannot think of anything else.

Arthritis in rabbits is very common so it's possible she is experiencing some of this and an x-ray would show that. An x-ray could also show possible bladder sludge as well.

Did the vet do a urinalysis too or just agree with what you said?

The vet agreed with what I said.
The vets that I have been to in my city are not very rabbit savvy. The place I currently go has a great reputation in town for dealing with 'exotic pets'.
They also seemed very reluctant to do an xray to check for arthritis and tried to talk me out of it. As that was one of the other things I thought it could have possibly been as well.

Also the vet didnt want to perscribe her any meds since they were concerned if she felt totally pain free that she would injure herself somehow. They did some stretching type tests on my bunny which were all fine.

Is there any rabbit vet nearby that could do X-rays? That's really the only way to know for sure if there are arthritic changes.
