    Best Overall: Oxbow Essentials Adult Guinea Pig Food

    If you’re looking for a pellet food that’s high in vitamin C and fiber, the Oxbow Essentials Adult Guinea Pig Food is a great choice. This 10-pound bag is affordable, but also made with high-quality ingredients. Each serving contains 14 percent protein, 25 percent fiber, 2 percent fat, and 10 percent water, and an optimal calcium-to-phosphorus ratio for healthy body weight. It’s lower in protein, calories, and calcium than standard alfalfa-based pellet products. Oxbow Essentials should be fed alongside a healthy dose of treats and hay.

    Reviewers say Oxbow keeps their guinea pigs happy and healthy. Not only do small critters love it, but because it has less fat than many competing brands made with alfalfa, it’s a great food for aging pigs who don’t need the same level of calories. If you are hunting for a high-end but affordable pellet, Oxbow is a great choice.

    Best Hay: Oxbow Western Timothy Hay

    Most small pets, including guinea pigs, need hay to help digest food and maintain clean, healthy teeth. Oxbow Western Timothy Hay is high in fiber and low in protein, so it’s perfect for adult guinea pigs. Up to 75 percent of your adult guinea pig’s diet should be made up of hay, so it’s important to pick a quality product to keep your pet healthy. Woven by hand, this hay is created without wires, thread or chemicals. It comes in 9, 15, 40, 50, and 90-ounce bags and is made of 7 percent protein, 1.5 percent fat, 32 percent fiber, and 15 percent moisture.

    Owners remark that Oxbow Western Timothy Hay is incredibly fibrous and contains more stalks and less filler than other products. Some note that the smaller bags contain more chopped up hay, but overall reviewers say this timothy hay is worth it for the quality and freshness you receive in every bag.

    Best Budget: Hartz Small Animal Diet Guinea Pig Food

    For less than $10 per 10-pound bag, Hartz Small Animal Diet Guinea Pig Food is a great value while still providing the nutrients your guinea pig needs. Fortified with vitamin C and high in fiber, this pellet food is made with dehydrated alfalfa and contains antioxidants and omega-6 fatty acids for a healthy heart and coat. It contains 13 percent fiber, 1 percent fat, and 25 percent fiber, and should be fed along with hay and treats. Each bag has triple-fresh seal packaging to keep your pet’s food fresh and safe and make pouring easy.

    Guinea pig owners say Hartz is a great lower-cost food that pets love. Each bag contains a mix of smaller and larger pellets, so some owners say their smaller pigs struggle to eat the larger pieces—if your guinea pig is on the smaller side, this food may not be optimal for him. Overall, Hartz has highly positive reviews and many happy customers.

    Your young, growing guinea pig has different nutritional needs than an adult guinea pig, which is why Oxbow Essentials Young Guinea Pig Food is created just for pets under six months.

You can feed unlimited pellets along with grass hay to your young guinea pig. Pregnant or nursing guinea pigs can also receive unlimited pellets and grass hay, as well as alfalfa hay in small quantities.

    Best Vitamin C Supplement: Oxbow Natural Science Vitamin C Supplement

    Unlike humans, guinea pigs cannot produce vitamin C on their own, so it’s important to feed them a healthy dose to keep their immune system in check. Oxbow Natural Science Vitamin C Supplement is a supplement you can feed your guinea pig in addition to his food. Each hay-based, high-fiber tab is made with timothy grass and contains 10 percent protein, 5 percent fat and 12 percent fiber. A bag contains 60 tablets, and the recommended dose for adult guinea pigs is one tablet per day.

    Owners say their guinea pigs love the Oxbow Natural Science Vitamin C Supplement, and most state that they see a marked difference in their pig’s health when feeding them. If you want to ensure your guinea pig is getting a healthy dose of vitamin C, a supplement can be a great addition to their regular meal routine.

    Best Treats: Kaytee Baked Apple Timothy Biscuit Small Animal Treats

    A healthy treat is an important component of a well-rounded guinea pig diet and we love the Kaytee Baked Apple Timothy Biscuit Small Animal Treats.
