I don't know about the rest of you, but in my experience, trying to get a rabbit to try a new food is often a hugely frustrating experience. Karnage was a particularly fussy eater; I don't know how much money I spent on various snacks and other goodies just to have him turn his nose up at them. Yogurt drops were the only things that he ever latched onto immediately.
Mickey's slightly more interested in trying new foods, but he is extremely hesitant to try something on the spot; I either have to leave it in his cage for a day or so and hope he decides to try it, or put it on the floor when he's out and about. I'm not sure if this is because of his early life in someone's basement or not, but he likes to eat his food off the floor. I usually put it on a paper plate or a plastic lid to try to keep my floor clean, but it's often a futile gesture; he just tosses everything off whatever it's placed on, then he'll eat it off the floor.
The newest additions to his diet are fresh papaya and pineapple juice, neither of which went over big at first. I figured that the papaya wouldn't be a big deal because he loves his dried papaya, but he completely turned his nose up at it. I tried wiping a little piece onto a paw, but he just shook it off and gave me a look that said, "What on earth are you doing, silly Mum?" Today, I put a few small scoops in one of his crocks instead of giving him his carrots. He sniffed at it, shuddered, then laid down for a nap. When I went to let him out this evening for exercise, however, the crock was empty. A couple pieces were on the cage floor, but the rest was gone. That's a relief; fresh papaya's damn expensive, and I was not looking forward to possibly having to toss it out because it wasn't getting eaten.
The pineapple juice was on recommendation from the vet because of his tummy issues--her orders were to give him a couple teaspoons via syringe twice a day to help with digestion and get more fluids in him. I was not at all optimistic about this. I'd tried offering him pineapple chunks recently, but he ignored them completely--wouldn't even touch them on the floor. I tried putting some juice in a small dish and leaving it in his cage, but by evening, it was still untouched, so I knew I'd have to syringe some into him. I don't like force-feeding a rabbit unless it's a medical emergency, and the times I'd tried force-feeding Karnage when he was ill were largely unsuccessful, so I was not looking forward to trying to get a syringe-full of juice down Mickey's throat. Sure enough, he was not having any of it at first, and I got more on his ear and face than in him because he was struggling so much. (It didn't help matters that my son was watching the whole procedure and laughing at us.)
Once Mickey actually got the juice in his mouth, though, he stopped struggling. I gave him a second to let things sink in; his tongue was going a mile a minute and he had a look on his face that said, "Oh, hey, this isn't so bad after all." I put the syringe in his mouth again and this time, he let me give him the rest of it. I've left the remainder of the juice in the dish in his cage in the hopes that he'll drink it. If he does, that means I won't have to keep using the syringe, I'll just keep using the dish. If he doesn't, then I'll have to stick to the syringe.
