Greetings,

I'm a bit new to the bunny culture. I recently adopted (inherited?) two male bunnies from a college girl who "had to get rid of them" asap. I'm known as an animal lover, so naturally, they moved in. I've never had rabbits before, and have done a lot of research. My boyfriend works for a vet, so we had them neutered right away. Normally, they are super sweet with one another, and I think they are brothers. They are about 8 months old and weigh 3.5 pounds. Every once in a while, Henry humps William, and this morning Henry was chasing William around their condo, almost aggressively. William was breathing very heavily after this "game." Do I need to be concerned about them sharing a living space? They live in a 4 by 4 foot condo, and they come out to play as often as I can manage. Like I said, they are very loving 99% of the time. Should I do something about Henry's aggressive behavior?

Thank you so much, both of you. That is what I suspected, but I wanted confirmation from some more knowledgable bun parents.

Help! As of yesterday, Henry's aggressive behavior seems to have returned. He chases William nonstop and pulls out his fur. I haven't seem any lacerations on William, but he is visibly shaken. This began while they were both romping in my room yesterday. After about an hour of them "hanging out" calmly, Henry started to pursue William. I noticed tufts of fur all over the room within ten minutes. Last night they calmed down for a while, but for hours this morning Henry continued his pursuit. I let William out of the condo alone so he could chill out.

What should I do? These boys grew up together; they're probably about 10 months old and are neutered. They seemed to have a very loving relationship before this.
