I’m a beginner with my recent new rabbit Shadow; and I’ve been wondering how do people get their rabbits to love specific fruits and vegetables so much? I’d see posts like “my rabbit loves strawberries/bananas”, can I can’t feel but to feel I’m doing something wrong by not giving my rabbit the same experience. Whereas I can barely get my rabbit to like anything else other than carrots ( treat purposes of course. ) 
When I first got him, I gave him a carrot–without repetitive introduction myself, he devoured it and goes bonkers for them every time he sees one in my hand. But anything else that isn’t a carrot for treats, he’ll turn his head away. I tried to have him try a grape, pretty much putting it in front of him, he took some interest in it as he nipped it scarcely, then deciding to cut it in half due to the amount of sugar contains it has, figuring it’d be easier for him to eat but still turns his head away from it. The same thing goes with trying to give him a fresh strawberry, or a slice of apple or share a banana with him. I even tried lettuce, wouldn’t eat that either.
