I'm changing her to a food called Hazel Hamster Food which doesn't have any added sugar, and it's the best food out there to use for your hamster if they have diabetes, as long as you take out the corn, and peas. I was giving her pellets and nutriphase gold, but she can't have those anymore obviously since it has things in it that she can't eat. Is it okay for me to just change her food straight to the new one, or do I have to gradually change it over a week? Not really sure in this situation. Right now she has half and half. I gave her a food bowl full of the new stuff with the corn/peas taken out, and then I have another food bowl with her old food, with the corn/peas taken out, along with the sunflower seeds, as she can only have those in moderation.
