Maybe. Or maybe he’ll teach the new bun his scratching habit and then you’ll have two bunnies scratching you! I think Sarita is right, he’s probably doing it to get your attention. Leroy does that sometimes too when I’m giving him his dinner and not moving fast enough. Like, “Hurry up mom! I’m STARVING! It’s been a whole two hours since I last had anything to eat… see? I’m withering away!”
Hehehe. And if you respond by petting him or… giving him food… it’s encouraging that bad behavior. Tell him no or make a sharp high pitched yelp, and then don’t give him his dinner until he’s forgotten about scratching you. Also, you can avoid that behavior entirely by shutting him out of the room while you’re putting down his dinner, and then call him for dinner once you have it set up. Or if he’s nearby, just put your hand firmly on his shoulders to hold him still (but not so firmly that you squish him!) while you’re getting dinner ready with your other hand. Or maybe he want’s some other toys and things to play with?
If you want to get another bunny, DJ will probably like having a girl friend (kepp in mind, some bunnies are perfectly happy having their slave all to themselves!), but just make sure you consider everything before getting another bunny. And don’t expect a friend to solve his scratching issue…
