AWW, she’s cute. Welcome home Patina! How does she react to Fujoes mounting?
Along with his hormones, it could be part of his dominant nature to mount for dominance. She may even try it on him. If she seems to take it for a little bit, then if she will allow you to pet her while it’s happening, sometimes that can help. Also, allow him to mount, but not for more than 20 seconds at a time to give her a break. Otherwise she could get really bent, and fight. Between each mounting, allow a minute or so break. (and of course don’t let any bunny mount the other’s head. They can actually bite the other in very painful place!!! YEEOUCH! I am betting you already know this, but just in case)
Where do you have your bonding sessions? Two dominants of the opposite sex can usually work things out, but one will have to back down to become the less dominant (notice how I don’t say..become passive) Rucy and Jack are two dominants. Rucy backed down during the bonding, and she does give way to Jack every once in awhile now, but she is clearly not passive.
If you haven’t already, you could use a stunt double for Patina, and put it in Fujoe’s cage so he can mount it and work out some of his issues of dominating and mating. It also might be a good idea to entice him to mount the stunt double just prior to your bonding sessions (by moving it around and circling him with it) so that he’s a little more tired during his actual bonding sessions.
Make sure the stunt double really smells like Patina. Have it in her cage over night, also if you can, brush her hair, take the fur from the brush, cut a small hole somewhere in the the stunt double (usually somewhere in the face, and/or hiney – I know…how nice), and put the fur there with a little bit sticking out. These are places that bunnies want to sniff, so having the hair there offers a stronger scent to make some bunnies accept the stunt double as possibly the other real bunny…or at least close enough to count.
Keep us updated!
