@MyBunBun – sorry I thought I replied to this! This can be checked by a vet using an otoscope to look into the back of the mouth. Wick’s vet says they see a lot of bubbles, and that means excessive salivation. I recommend a veterinarian trained for rabbits to examine it formally.
@missyprincess – Sorry to hear of your struggles! It would be best to make your own topic to get some responses from BB members. Know that not every rabbit picks up on litter box usage naturally (Wick definitely did not), so training, sometimes more involved training is needed. If he’s in the box while he’s peeing outside of it, I recommend getting a high-wall litter box. Rabbits won’t really think of where their pee lands, but he probably believes it’s in the litterbox because he’s sitting in it. So to him, he’s being good, although his pee stream thinks otherwise.
