Best food for guinea pigs – Buyer’s Guide

What Should You Feed A Guinea Pig?

Guinea pigs are herbivorous animals that spend hours eating grass. They have unique teeth that grow continuously, hence the need for a high roughage diet that encourages chewing. This helps wear down the teeth and ultimately prevent dental problems. It is also important to provide sufficient fibre for the gastrointestinal system as well as general health.

The ideal guinea pig diet should contain the following:

Grass hay

The most important thing to include in a guinea pig’s diet is high quality grass hay. These animals require an abundant supply of grass hay for proper digestion. It provides the fiber that a guinea pig needs to digest and process food content. The lack of a constant supply of grass, your pet’s digestive tract is highly likely to shut down. In addition to digestion, grass hay helps guinea pigs clean their teeth and prevent the teeth from growing too long.

An important thing to point out is that even though it isn’t green, hay doesn’t come with any side effects for your pet. There are many varieties of hay and it’s important that you only purchase the best. High quality hay should have pliable stalks. It should also be free of fragrance, mold or foreign particulates. Some good examples include alfalfa hay, Timothy hay, meadow hay, brome grass hay, orchard hay, bluegrass hay and oat hay.


Guinea pigs also thrive on processed pellets. They are cheap and readily available, hence a common favorite. We recommend giving your guinea pig up to 1/8 – 1/4 cup each day. This should be enough along with other foods. There are many varieties of processed pellets on the market and such, it is important that you purchase ones designed for guinea pigs rather than rodents and rabbits.

Fresh vegetables

Fresh green vegetables play a crucial role in a guinea pig’s diet. That said, always ensure that your cavy a cup of vegetables each day. You must have a constant supply of vegetables so as to maintain a balanced diet.  Some of the beneficial vegetables for cavies include tomatoes, carrots, raw broccoli, beetroot, celery, spinach, cucumber and peas just to name a few. 

Vitamin C is a MUST!

Like humans, guinea pigs cannot synthesize vitamin C. As such, they have a serious deficiency of this nutrient. A good way to combat this problem is to ensure they eat 10-30 milligrams of vitamin C on a daily basis. They need to get it from their food and a great way to achieve this is to feed them fresh vegetables and fruits.

It is important that guinea pigs can be very choosy about what they eat and as they grow older, what they love to eat changes. Ensure that your cavy has a constant access to hay and water through a drip feeder bottle. Using a platter for feeding purposes isn’t a bad idea either.

Which Foods Are Poisonous for Your Cavy?

There are several foods that you shouldn’t feed your guinea pig for different reasons. Some cause bloating and gas, some simply have no nutritional value, some are too high in sugar or fat and some are a choking hazard. Reputable pet websites like ASPCA have plenty of information on this information. However, it’s best to consult a veterinarian that specializes in small animals.

Examples of foods to avoid include dairy products, rhubarb, corn kernels, potatoes, avocadoes, mushrooms, onions, meat, garlic, chocolate, cabbage, peanut butter and seeds. Don’t offer your cavy any flowers, grass or plants from your backyard as they may contain pesticides.

Introducing New Food

Changing a cavy’s diet will prove necessary as the little creature becomes older. Like any other pet, this is something that should be done slowly and bit by bit. It is a delicate process and because guinea pigs are stubborn animals, they may not touch the food at all. In some extreme cases, they end starving themselves.

This is a common problem with mature and older pigs. That said, you will want to experiment with what your pet likes when it is younger. If it gets sick or behaves abnormally, remove any newly introduced foods. You should also consult a vet if there is cause for concern.


The most important thing when it comes to feeding your little pet is to ensure that they eat a balanced diet. There are some great options, aside from hay and vegetables, which you can find on the market. Look for pellets, preferably those without fruit bits or seeds as these have high fat content. They shouldn’t have any added colorful pieces.

Like with most products, more expensive brands usually offer higher quality food for guinea pigs. The cheaper varieties often contain artificial ingredients that aren’t good for your cavy. Other rules for purchasing guinea pig food include:

  • Plenty of vitamin C
  • Timothy hay rather than alfalfa hay since the latter is fatty
  • No corn as it doesn’t have any nutritional value
  • No chemical preservative or anything artificial
