My rats eat almost everything I eat but limited amounts as they pack on pounds (or ounces or grams they are so little) fast. For a staple diet they eat a rat/mouse seed mix w/ the lab blocks but everyday they get fresh veggies/fruit, a bit of cereal and a little of our dinner. My rats favorite is meat (only limited as it is hight in protein). They love cheese too! I keep a string of raw pasta hanging in the cage most of the time they love that too. There is not much that do not like! lol
