Agree with most of the posters above. Jam is such a high amount of sugar that I would avoid it altogether. Graham crackers and any processed food meant for people shouldn't be fed to bunnies. No candies, no chocolate, and definitely nothing that has dairy. Try some natural treats, there's bound to be something your bunny will love! Bananas (a small chunk), a slice of apple, pear, or the peels would be delish. My buns also like it when I slice off the top of my strawberries and give them them the tops. It has a bit of green on it and it doesn't have as much sugar as the rest of the berry. Some bunnies love love love parsley or cilantro or dill. Dried fruits are also delish but be aware that the sugars are concentrated in dried fruits so feed them less than you would fresh fruit. Raisins, Craisins, papaya are all welcome treats in my bunny household.
