The 10 Best Guinea Pig Foods & Pellets

It is generally known that guinea pigs, like many other small livestock, need a significant amount of hay each day.

This will provide them with the fiber they need for good digestion as well as the chewy food they need to maintain a youthful set of teeth.

That said, guinea pigs are very versatile and can accommodate a wide range of diets with their fiber needs.

Among commercial guinea pig feeds, pellets are the most popular.

Pellet meals will provide your guinea pig with a nutritious, balanced diet, as they can't pick the good ones and leave the good ones behind.

A good pellet food will give your guinea pig the fiber and vitamins and nutrients it needs for healthy teeth and bones, a healthy coat, and a strong immune system.

It can be difficult to find the best foods for your loved one. To save you time and energy, BestForPets (bestforpets.org) researched and reviewed a wide variety of guinea pig foods to help you choose the best guinea pig foods & pellets for your pet.

Instruction Manual for Shoppers

You should feed your guinea pigs pellets. They have the potential to supply your guinea with the full spectrum of nutrients it needs to thrive, from protein and fiber to vitamins and minerals.

Your guinea won’t be able to pick out the delectable goodies and leave the healthy bits of the pellets, because the pellets contain everything your guinea needs. When selecting guinea food, there are a few things to keep in mind.


Guinea pigs require a high-fiber diet. This promotes good digestion and helps their rapidly developing teeth stay nice , short and strong. Alfalfa hay and timothy hay are common sources of the fiber.

Adolescent guineas benefit greatly from alfalfa hay, but feeding large amounts to adults is not recommended. Vitamin C is an essential nutrient for guinea pigs, who are unable to produce it themselves.

Essential oils included in omega-3 fatty acids are beneficial for your guinea’s skin and coat.

Things to Stay Away From

It’s vital not to offer your guineas heavy quantities of sugar, as this can lead to obesity and even diabetes. Pellets with additional fruits and vegetables should be avoided or used sparingly.

Dried fruit is one component of these mixtures, but some also include seeds and nuts, which are not guinea pigs’ natural diet. Your guinea will certainly appreciate these snacks, but they should preferably only be given as an occasional treat.

Any forms of artificial colorants or flavors should also be avoided, as they might create health difficulties.

Only young guineas or guineas who are pregnant or nursing should be fed alfalfa hay because of the high levels of calcium and fiber it contains.

Overfeeding your guinea alfalfa, which naturally contains a lot of calcium, is not necessary after your pet reaches adulthood, and may actually be harmful to its health.
