Oxbow Essentials Adult Guinea Pig Food

Oxbow Essentials Adult Guinea Pig Food is made with timothy hay—which is rich in fiber—and fortified to provide 100 percent of the vitamins and minerals a guinea pig needs each day, including vitamin C and prebiotics. Plus, the food contains no artificial preservatives, colors, or flavors.

Oxbow Animal Health has been an industry-leading manufacturer of small pet food since the 1980s, and its hay is sourced from farms in Nebraska. The brand's Essentials Adult Guinea Pig Food is made into small pellets with a uniform shape and size.

Each serving will provide a consistent texture that is free of seeds, making the food more likely to appeal to picky eaters. Guinea pigs are known for being selective when it comes to their food, and some will avoid eating select shapes and textures (like seeds) in their bowl. If this sounds like your cavy, it might mean they are missing out on the full nutritional benefits of their food, and you should slowly transition them to a food with a consistent texture, like Essentials Adult Guinea Pig Food.

The food is packaged in three bag sizes, 5, 10, and 25 pounds, and all are equipped with a resealable zipper at the top. The larger bag of pellets may be less expensive per pound, but if you only have one or two guinea pigs, the vitamin C in the food will likely expire before your cavies can consume it all. The food is not suitable if your guinea pig is still growing, gestating, or lactating.

Best Hay

Oxbow Orchard Grass Hay Small Animal Food

$12 at Amazon $12 at Chewy View on Petco

Schubert says orchard grass is very soft and sweet and is less likely to stick in the coats of the long-haired pig. It is also less likely to poke an eye. These characteristics make it a favorite hay among guinea pig owners and breeders.

Multiple-sized bags or bales are available, so you can be sure to only buy as much as your guinea pigs will eat in a timely manner. “There never can be too much hay in the cage," Schubert says. "It is a staple that can be offered free range.”

Best Treats

Kaytee Timothy Biscuits Baked Treats

More fiber is always welcome in a guinea pig's diet, and Kaytee Timothy Biscuits Baked Treats are high in fiber from natural timothy hay grass. The crunchy treats will appeal to your guinea pig's chewing instincts, and mastication is beneficial to their dental health.

The tasty treats come in two flavors, carrot and apple, each made with the real fruit or vegetable. The baked biscuits are packaged in bags and sold in two sizes, 4 ounces and 10 ounces.

Kaytee recommends feeding your guinea pig by placing the treat in the palm of your hand or in a dish, but give these in moderation. In general, treats should be given as a supplement to a guinea pig's diet and should account for 10 to 20 percent of your guinea pig's total daily calorie intake to avoid unintended weight gain.

These treats are made in the United States and are beneficial for other small pets, such as rabbits, chinchillas, and hamsters. The serving size direction is vague to address the needs of various small animals, but we recommend one or two per day for most guinea pigs. Each biscuit contains approximately 9.5 kcals, and a biscuit can be broken into smaller pieces.

^{Key Ingredients: Wheat flour, sun-cured timothy grass hay, soybean oil, dehydrated apple, flaxseed, wheat middlings, ground wheat, oat hulls, dehulled soybean meal, dehydrated alfalfa meal, dried cane molasses (apple flavor) | Recommended Daily Serving Size: Up to 20 percent of total daily food intake}

Best Budget

Kaytee Forti-Diet Pro Health Guinea Pig Food

$17 at Amazon $9 at Chewy View on PetSmart

Each serving of Kaytee Forti-Diet Pro Health Guinea Pig Food is formulated to provide a cavy with a nutritious meal rich in protein, omega-3 fatty acids, probiotics, and prebiotics to support their overall health, immunity, and proper digestion. The pellet-shaped food encourages guinea pigs to chew, which can help reduce buildup on their teeth, and the food is generally more affordable per ounce than other options that made our list.

The guinea pig food from Kaytee is manufactured in the United States and was developed by an animal nutritional expert. Depending on the size of your guinea pig, you might feed 1/8 to 1/2 cup of pellets per day and supplement it with hay and fresh vegetables to give your guinea pig the variety they need.

The food is packaged in resealable bags that come in two sizes: 5 pounds or 25 pounds. There are cost-effective savings with the larger bag, but if you only have one or two guinea pigs, having 25 pounds of food on hand might last longer than a year and compromise the freshness of the food.

^{Key Ingredients: Sun-cured alfalfa meal, ground corn, dehulled soybean meal, ground oats, ground wheat, ground flax seed, dicalcium phosphate, dried cane molasses, soy oil, ground rice, salt, calcium carbonate, magnesium oxide, potassium chloride, algae meal | Recommended Daily Serving Size: 0.125 to 0.5 cups per day (adjust portion for proper weight maintenance)}

Oxbow’s Organic Bounty food is a high-quality option if you are looking to feed organic food to your guinea pig. “Oxbow makes a superior food, so on a small scale, if you only have a couple of guinea pigs, I recommend feeding this,” says Schubert.

A 3-pound bag of food is a great size for one or two guinea pigs, because it will help ensure that you are always feeding fresh food with effective vitamin C. This food has the USDA organic seal, which means the ingredients are grown by certified organic farmers, but the price point will be higher than that of other foods.

_{Key Ingredients: Organic grass hay, organic canola meal, organic wheat straw, organic sunflower meal, organic barley, organic flax seed, yeast culture, sodium bentonite, limestone, salt, vitamin C, organic dandelion leaf | Recommended Daily Serving Size: 0.125 cups per day}

Best for Baby Guinea Pigs

Oxbow Essentials Young Guinea Pig Food

Schubert suggests that the best food for baby guinea pigs is "a higher protein food that is around 18 to 22 percent protein.” That means that Oxbow’s Essentials Young Guinea Pig food is a great choice for guinea pigs less than six months old.

These pellets contain no seeds and have a minimum of 18 percent protein in each serving. They are also made from alfalfa hay and not timothy or orchard grass to provide the different nutrients growing cavies need. Guinea pig owners also rave about how their growing pigs love this formula.

_{Key Ingredients: Timothy grass meal, soybean hulls, wheat middlings, soybean meal, cane molasses, sodium bentonite, soybean oil, salt, lignin sulfonate, limestone, yeast culture, vitamin C, vitamin E supplement | Recommended Daily Serving Size: Unlimited}

Best for Vitamin C

If you are concerned about not giving your guinea pig enough vitamin C, Oxbow’s Natural Science Vitamin C Supplement is a great option to provide to your cavy. These treats are also high in fiber to aid in digestion and help prevent diarrhea.

Plus, guinea pigs love them, and owners say their pigs come running for their vitamin C. The supplement is also suitable for other small pets such as rabbits and chinchillas, but whenever adding a supplement to your pet's diet, it's always a good idea to consult with your vet.

_{Key Ingredients: Timothy grass, barley flour, oat groat flour, cane molasses, vitamin C, flaxseed meal, brewers dried yeast, guar gum, fat product, rosemary extract | Recommended Daily Serving Size: 1 tablet per day}

Best Chew

Vitakraft Guinea Pig Treat Sticks

$4 at Amazon $6 at Chewy $6 at PetSmart

Each Vitakraft Guinea Pig Crunch Stick comes with a plastic hook to make it easy to hang in your guinea pig's cage. It's made with a chewable natural wood core and covered in dried fruit, honey, corn, oats, and other crunchy treats to support dental health.

Each stick is about 9 inches tall, supplemented with vitamin C, and triple-baked for a fortified consistency that's designed to optimize a guinea pig's teeth. The treat comes in multiple flavors, including Apple & Orange, Fruit & Honey, Wild Berry & Honey, and Grains & Honey.

_{Key Ingredients: Wheat, wheat flour, yellow millet, corn, ground grain sorghum, heat-processed oats, corn starch, oats, oat groats, buckwheat, dried figs, dried apricot, peanuts | Recommended Daily Serving Size: As needed for dental maintenance}

Best Compressed Hay

Oxbow Harvest Hay Stacks

$11 at Amazon $11 at Chewy

$19

$11 at Petco

Oxbow Animal Health Harvest Hay Stacks are made using only timothy hay, which is a type of hay made from leaves and stems from timothy grass. The organic matter is then compressed and hand-sorted into portions referred to as stacks. There is no limit on the number of stacks you can give your guinea pig each day, and this hay is high in fiber, which helps support the dental and digestive health of your pet.

Oxbow recommends placing a few stacks in your cavies' dwelling each day in an S-shape to watch them enjoy chewing while they intake the nutrition they need. While your guinea pig is extremely likely to love this hay, it will inevitably result in a mess that you'll need to tidy up.

Best Sticks

SunGrow Sweet Bamboo Chew Sticks

View on Chewy

SunGrow Sweet Bamboo Sticks are formulated for rabbits, hamsters, guinea pigs, chinchillas, and other small furry pets. The sticks are an ideal snack and chew toy for guinea pigs because they're low-calorie, high-nutrient, and high-fiber, so they won't contribute to obesity and health issues. Plus, they're made without dyes, artificial flavors, and artificial colors.

The sweet flavor makes them more appealing and encourages guinea pigs to happily gnaw away as they trim down their teeth. Each package contains about 8 sticks, making this a rather pricey treat. Nevertheless, these sticks provide a good alternative to seeds and sugary snacks while aiding dental and digestive health.

Best Critical Care Food

Oxbow Critical Care Herbivore

$20

$15 at Amazon $11 at Chewy

Long considered the golden standard in recovery food for guinea pigs, Oxbow's Critical Care Herbivore was developed by small animal veterinarians and nutritionists to provide essential nutrients, minerals, and vitamins in an easily digestible form for sick guinea pigs, rabbits, chinchillas, and other small herbivores. Like the brand's other formulas, this one is high in fiber—timothy grass meal, soybean hull, and soybean meal are at the top of the ingredients list—which helps stave off GI stasis. This food is also low in carbohydrates and contains all-important vitamin C, beneficial prebiotics, and readily absorbable chelated minerals.

It comes in three flavors of powder that's easy to mix to your desired consistency, so you can feed your pet in multiple ways: tube or syringe-feed, spoon-feed, or in a bowl for self-feeding. The papaya flavor is the only one that is fine-ground, which many pigs prefer over the apple & banana and anise options. However, the papaya flavor is harder to find and often comes in only one size, whereas the other two are available in three sizes.

_{Key Ingredients: Timothy grass meal, soybean hulls, soybean meal, wheat germ, soybean oil, xanthan gum, potassium chloride, salt, vitamin C, flaxseed, magnesium sulfate, calcium chloride, papaya, pineapple, cane molasses | Recommended Daily Serving Size: 4 to 6 servings per day}
