10 Best Guinea Pig Foods & Pellets 2021 – Reviews & Top Picks

Nicole Cosgrove

guinea pigs eatingGuinea pigs, like most other small pets, need a large amount of hay for an optimal diet. This will give them the fiber they need for healthy digestion and provide the essential chewing fodder to keep their teeth short. That said, guinea pigs are adaptable and can do well on a variety of foods alongside their fiber requirements.

Pellets are the most common form of commercial guinea pig food. Pellet-based foods will give your guinea pigs a healthy, balanced diet, as they cannot pick out the treats and leave behind the healthy foods. A good pellet will provide your guinea pig with essential fiber and all the vitamins and nutrients they need for healthy teeth and bones, coats, and immunity.

It can be confusing to find the right type of food for your furry friend, one that will keep them both happy and healthy. We’ve done the hard work and put together this list of in-depth reviews to help you narrow down the options and find the best guinea pig food for your beloved pet.

    Buyers Guide

    Pellets are the best form of food to give your guineas. They can provide the complete profile of nutrients that will keep your guinea healthy and happy, including protein, fiber, and vitamins. Pellets have everything your guinea needs, so you can be sure that it will not just eat the tasty treats and leave behind the nutritious parts. There are a few factors to consider when purchasing food for your guinea.

    Ingredients

    Guineas need fiber in their diet. This keeps their digestion healthy and keeps their fast-growing teeth short and strong. The fiber usually comes in the form of alfalfa hay or timothy hay. Alfalfa hay is great for adolescent guineas but can be dangerous for adult guineas in big quantities. Guineas cannot make vitamin C, so they need it as a daily part of their diet. Omega-3 fatty acids are also important, as they will give your guinea essential oils that help maintain healthy skin and coat.

    Foods to Avoid

    It’s important not to give your guineas high amounts of sugar, as this can lead to obesity and even diabetes. Pellets with added fruits and vegetables should be avoided or used sparingly. Some of these mixes also contain seeds and nuts in addition to dried fruit, which are not natural foods for guineas. Your guinea will likely love these treats, but they should ideally only be given as an occasional treat. Any kinds of artificial colorants or flavors should also be avoided, as they can cause health issues.

    Alfalfa hay is a great source of calcium and fiber but is suited only to young guineas or pregnant or lactating guineas. Adult guineas past six months of age don’t need high amounts of calcium, which alfalfa contains in fairly high amounts, and this can cause health issues if you give too much of it to your guinea.
