My Bernie humped every new rabbit we introducedhim to except Oreo. Oreo wouldn't let him and they would start tofight. But Bernie shares a bedroom with 3 other rabbits and they areall submissive to him. They are all happy with this arrangement exceptmaybe Alice. Alice isn't fixed yet so she'll hop by Bernie, stop andmount his head and then run off before he can do anything. They'refunny. I think the mounting is just a dominance thing and it's fineunless they're opposed to being mounted and fight back. Just my opinion.
