Regarding baby food, you really need to find out what flavors they do or don't like as all rats are different. My boys always loved squash and peas baby food but for some reason they did not like the fruit kinds, like banana, etc. Just personal preference. I guarantee though, that once you find a flavor they love, they will LOVE it. I never gave my boys dried fruit because it has so much sugar and can sometimes be flash fried or whatever that term is. Fresh fruits are always better. They don't really need to have any dried fruit in their food mix.
