What does his daily diet consist of? I know some veggies can make urine more stinky (however, I can never seem to remember exactly which ones…) The pooping might still be territorial marking, some buns will always mark their area, even years post-neuter. Is he using a litterbox in addition to the marking? Humping between a pair is typically their way of working out their dominance issues, or it could be a sign of excitement or insecurity. As long as they are not humping facing the “wrong” direction (August humping Buster’s head) and there is no aggression between them, there is no real danger in the humping. My pair will hump each other several times thru out the day, and they’ve been bonded for a year. I think it’s just them expressing their love of the other.

Are they living together full-time or you’re still doing bonding sessions? Another member mentioned that her not-quite-bonded pair would hump when they were first brought together for a session, it was almost like their way of saying “hi!”

I think as long as the humping doesn’t bother Buster then you should not worry about that. If Buster is not happy with the humping he will try to get away or let August know. It sounds like August too is still going through puberty and some rabbits really are just better at the litter box than others.

Makes me wonder if perhaps Buster has some kind of urinary infection since you his urine smells so bad.

It sounds to me like August was peeing over the side of the litterbox – sometimes they stick their hind end up and instead of peeing in the box they miss the box. If that is the case then perhaps a high sided box might help.

When my rabbits have urinary tract infections I can usually tell because they don’t use their litter boxes – I’ll see wet spots everywhere. Mine will usually continue eating and drinking they just cannot control their bladders. Usually their urine smells stronger too I guess from the bacteria and inflammation. I’m sure they are uncomfortable but not uncomfortable enough to eat (certainly if it continued that could be the case that they stop eating).

Sometimes you might see them putting their tail up as well straining to urinate and maybe they will urinate and maybe they won’t but you can see them straining.

Someone last year had a good suggestion for an overly-humpy bunny, they put a box or something just big enough for one in the pen so the humpee could scoot in and get away from the humper.

My senior couple like to do it in front of the younger rabbits and before you know it, they’re ALL humping! competitive bunch.

Beka – I think it’s Basil that makes urine extra smelly.

UTI’s can definitely affect the smell of urine too, so it would be a good idea to have him checked out. Do you notice any of the symptoms that Sarita described?

Thank you BB! I always forget what specifically it is ;o) You would think I’d take a moment to write it down, but I’m sure I’ll forget by tomorrow! lol…
