I think its pretty cool to see what the animals at the pet store eat and how they eat. For example how the rabbits and guinea pigs eat generally the same thing hay, vegetables, food pellets, and some fruit(apples). Hamsters are a little different they just get feed a premixed bag of food such as corn, sunflower seeds, hay, peanuts, alfalfa, and lots more. Everything the hamsters will eat is in the premixed bag that you can buy. Most rodents are vegetarians meaning that they do not eat meat. Except wild rats and mice eat pretty much what ever they can, so grains, fruits, vegetables, seeds, nuts and what ever they catch.
