Everything I do offends Otto - he's kind of a grouch
He gets annoyed if I pet him usually and will sometimes use his face to push my hand away as hard as he can. A few times he's even put his teeth on me when he did it, but without biting down. The only time he's ok with pets is when he's snuggling up to Hannah - then he loves it (maybe he thinks she's the one grooming him? haha). He's become fairly easy to pick up, but he is also very offended by it and will stay mad for a long time. Hannah is impossible to pick up, but after you try it she'll come right back for pets and doesn't hold a grudge. Oh, Otto also gets offended when I offer him fruit - he loves dried fruit, but anything fresh gets me a death glare like I'm offering him poison.
Hannah gets really upset with being brushed or having tufts of fur plucked out of her bum. We've had her a year and somehow she's only gone through one shed, thank goodness, but her butt looked like a cactus for a month and she would run away and foot flick after one pluck. We try doing a little brushing while she's eating (this works for Otto) but she immediately grabs a huge piece of lettuce and runs off with it where we can't get her. She also gets offended occasionally if you stand in front of her and she'll run up to tug at your pants. It's not all the time and I'm not sure what she's thinking when she does it - maybe she wants us to get out of her way.
eta: Funny how so many rabbits get offended at the litter box cleaning. My two love it and will wake up from a dead sleep to check out what I'm doing and generally get in the way (sitting in the box so I can't pick it up, chewing paper towels, jumping in the cage just when I'm going to spray it down with vinegar, etc). It's like they're so excited the cleaning lady finally showed up
As soon as I put the boxes back they have to run in, eat some fresh hay, and generally check out how good of a job I did.
