Lupe and Buffy has been together for more than a year now.  They never have a big fight ever since they're bonded. They're staying in the same area at night or when I'm out, never been seperated. And eversince my schedule's change, I get to hang out with my bunnies more often. Lupe has always been the outgoing type and like to be cuddled while watching TV with me, she had been an only bunny for almost 2 years until I got Buffy.  While Buffy from the start is more mellow, and doesn't really like to explore that much and lounges alone So in certain times when I'm a home they spend time at different area. They would chase each other when they meet in the hallway and there's nipping involved. It happens mosty when I give them treats. But no hair pulling or anything serious. It makes me little anxious though. And they don't groom each other as much. So is this normal in bonded pair? Does any of your bonded pair fight at all?

Some rabbits can get a little more aggressive around food time (survival instinct), sometimes my male rabbit will literally take food away from my female rabbit's mouth. Now I'm just in the habit of feeding them in separate rooms or will sit down and watch them.

I too am wondering if they have been spayed/neutered?
