Hello! I was wondering if anyone could help me out. Well, i own rats-i love rats, i own many rats. The other day i went looking for some natural and healthy rat treats at the local pet shop, they didnt have much of a selection of healhty snacks, everything was pure sugar!!! so it got me to thinking about getting a dehydrator and making my own, i also started thinking about maybe selling some to my local pet shop to sell, as im sure im not the only rat lover who wants a healthy treats for there pet. SO, onto my question-if i did this, would i need to add a preservative to the dried fruits in order to store them in a sealed baggy NOT in the fridge?
