@Dark7_Lord It isn't really necessary to feed guinea pigs pellets, but it's recommended to do so. Pellets have an extra boost of Vitamin C in them, so unless you want to feed them extra veggies every day you need to feed them two portions of pellets a day if they're adults. Smaller piggies need three portions a day. Pellets are also good as an extra resource during the winter, as they'll need nutrients that they cannot get from vegetables, as the seasonal fruits and veggies may lack these nutrients. In conclusion, yes, you could feed your guinea pigs pellets and most owners do so, but you don't have to. Just keep in mind that if you choose not to, they'll need extra vegetables.
