Whether Feeding Rodents Citrus or not can be CONFUSING! It may be "no" on some websites or "yes" on another!
"My understanding of feeding any citrus fruits is that the acid contained in them is much too harsh on the lining of the hamster’s stomach! Keep in mind that they certainly won’t kill your hamster, but will upset the lining in their stomach. We certainly wouldn’t want that.

You can feed male rats pieces of peeled oranges if you're careful to wash it off after you have peeled it. Orange juice is safe to give to female rats."
" Our rabbits get orange pretty much every day during harvest season. I give them the peels of the fruit we eat, as well as fruit & peel from oranges that have fallen off the tree. In the beginning of the season they may get 1/4 orange each as a treat every few days, but as time passes the amount they get increases until the end of the season (which is really long for us as we harvest from January to June/July). Although I'll generally give them 1/4-1/2 an orange, when I have enough windfalls I'll give them a whole fruit each. It's amazing how quickly a rabbit can polish off a whole orange!"
"Anything acidic is supposed to be bad."
