I’ve had to deal with this a bit with one of my pairs. My 12 year old male bun, Bun Jovi, can go through phases of obsessive mounting.
Some things I’ve done:
- Added extra hides, platforms, and tunnels so she can get away from him, and made sure they have plenty of space to run around.
- Had Bun Jovi checked out by the vet for urinary issues, because bladder stones can cause excess mounting behavior. He was fine, but I recommend having your buns checked out too (both for issues with your girl and your boy)
- Removed dandelion and parsley from Bun Jovi’s diet, except in very small amounts. These two veggies are diuretics, and although I never saw anything about this in the forum or the literature, I had been feeding dandelion daily for a while, and when I removed it from the diet things calmed down a lot for him. Even now when I give him a dandelion leaf, I notice and uptick in mounting later that day. I still give it occasionally because it’s so nutritious but Bun Jovi doesn’t get as much as my other bunnies.
- On one extreme instance I did remove Bun Jovi for about 12 hours because I was worried he was going to have a heart attack from chasing her. But this was also right after moving and during an attempt to bond a quad, so I think it was all due to the bonding stress.
He has since calmed down a lot. He still chases her a bit each day, but it’s not extreme and she has plenty of places to take breaks from him if it gets to be too much.
