Best Guinea Pig Food Guide for Responsible Guinea Pig Owners

Do you have troubles finding the best guinea pig food, since there are so many options on the market? You even reading this makes you better than half of the other pet owners, who just buy the first thing they see at the store or the cheapest product, without even thinking of the quality of the food. Our guinea pigs are our responsibility, they depend on us. If you don’t eat unhealthy cheap products yourself, then don’t make your piggy do so.

What Do Guinea Pigs Eat Food?

We all know that guinea pigs are herbivorous animals so naturally grass makes the most of their diet. Aside from the grass, they eat their own poo; some animals tend to do so, it nothing to be alarmed about. They do not eat all of it; it’s just that guinea pigs poop out soft pellets. This part of the poop contains vitamin B, fiber and bacteria and these nutrients help guinea pigs in digesting food.

Vitamin C Is a Crucial Part of Guinea Pig’s Diet

Unlike some animals (like cats and dogs) guinea pigs can’t produce their own vitamin C, and that’s why they need to get it from their food. Listed below are human foods that guinea pigs can benefit from, by getting additional vitamin C boost:

  • apple
  • carrot
  • spinach
  • broccoli
  • celery
  • cabbage

Guinea Pig Necessities!

Did you know that our little puffy buddies’ teeth never stop growing? That’s why they always need to have something to nibble to grind their teeth down, or they’ll become too big for their mouths. Your guinea pig should have fresh hay and water in its cage at all times, hay is just perfect for a nibble, but you can try some other vegetables too. However they’ll chew almost anything (rubber, cloth, paper), so keep valuable things out of your guinea pigs reach.

How to Introduce New Food to Guinea Pig?

Guinea pigs can be quiet picky when it comes to a new food, to which some of you may think “Yea right, but poop tastes great”. But yeah, guinea pigs are even ready to starve themselves to death if they don’t like food you’re introducing.  It is better to do that when they are little. Or let’s say you wanted to introduce carrots into your guinea pigs diet, and he doesn’t like it. You can shred it into really small pieces and sprinkle it over piggy’s dry food.

Another thing we should be careful about when introducing new food to guinea pigs diet is we don’t know if he’ll react well to it. If you notice a behavioral change or loose stool, contact your vet immediately.  To avoid that always offer a really small piece of fruit or vegetable you want to add to his diet. If everything seems normal, you may continue with that food.

How to Choose the Best Food for Your Guinea Pig?

When is a search for the best guinea pig food we should look for one that doesn’t have colorful pieces, nuts, and seeds, or chunks of fruit since they are really high in fat and you don’t want an obese pig.  Try to find plain pellet food if you can, because those are the best for your pig’s health. If you can’t afford the most expensive brand, that’s fine, however, keep in mind that cheaper brands are bad in quality.


They taste great, your piggy will love eating them, just like we like eating fast food, but it doesn’t mean that it’s good for us. Your pet won’t be getting enough nutrients from them. You can find some good quality food for a reasonable price, and most importantly your pig will live a long and happy life. Never feed guinea pig with rabbit food. With that been said, it doesn’t mean that it’s bad. It’s just bunnies can produce their own vitamin C, while pigs can’t. And like we already mentioned vitamin C is essential for guinea pigs health.
