You could cut back on the pellets, but it would also be good to cut back on the fruit. Rabbits do get certain vitamins and minerals from the pellets. If you were to totally eliminate them, you are supposed to feed a variety of 15 different greens a day.

A half of a banana and a half of a carrot, in addition to some berries every day, is a lot of sugar. Some people recommend that rabbits don’t get any fruit, but you could cut back on the portions and let him have a little bit of fruit each day – either a small piece of carrot or a small piece of banana, plus a berry or two. It would also be good to give him more of a variety of greens. That way, Remus might not miss the fruit so much, plus he would be getting extra nutrients.

Here is a good article on greens, veggies and fruit with lists of ones to try. Go slow, don’t try a lot of new things at once. One new veggie a week would be good. http://rabbit.org/suggested-vegetables-and-fruits-for-a-rabbit-diet/

I’m not sure how to get him to exercise more, but that would be helpful.

My couch potato Bam can be made to exercise with a treat ball. So I give him his pellets in the treat ball (when I don’t just hand feed him his pellets as treats). He too needs to get very little pellets and very little fruit. Carrot is to be regarded as a fruit. Berries are lower in sugar than fruit (grapes don’t count as berries though).

Leafy greens like fex romaine, red and green leaf lettuce, dandelion or spinach, and fragrant herbs are very low cal, so there’s no need to cut back on those. When I had to diet my Bam he got lots of fresh low cal veg so he’d not be so hungry. The amount should be increased gradually-all dietary changes for a bun need to be done gradually to not cause tummy trouble.

You don’t necessarily need to give up on the treat ball yet -it took my Bam 1,5 YEARS to figure out how to work it

(I kind of wish I was exaggerating, but I’m not.)
