Best Guinea Pig Food for 2020

A guinea pigs diet is mostly made up of grass, nutritional pellets and a small number of fresh vegetables daily.

Unlike a lot of other animals, guinea pigs can’t formulate Vitamin C by themselves. Pellets and suitable vegetables should be packed with this, so are a great way for them to get all of their daily intake of nutrients without the feeding process becoming too complicated.

Hay doesn’t provide much nutritional value but is needed in order for their constantly growing teeth to stay ground down and to regulate digestion.

These are the best hay and pellet options for your guinea pig’s diet.

    Oxbow Orchard Grass

    Orchardgrass hay has a sweet, fresh taste and smell which animals can’t resist (according to Oxbow and a whole host of animal owners).

    Burgess Excel Herbage Timothy Hay

    Timothy hay is perhaps the classic blend and variety, and hay, in general, is the best source of fibre for any small animal to keep their digestion in check.

    Nature's Touch Guinea Pig

    A complete food such as this is best suited to guinea pigs who haven’t displayed fussy or picky eating in the past, and given as an addition to hay.

    It contains a blend of hay, vegetables, flowers and plants for some variety, which is great if you don’t want to give them the same old hay and pellets every day, or if they perhaps don’t like nuggets or greens.

    The pellets included in this blend are smaller than standalone options, which will also be welcome for smaller breeds or those who don’t seem to touch standard sizes. There is a great number of stalks included too, which gives them the tougher texture needed for teeth health.

    Mixing a little bit in with their hay means they shouldn’t get too addicted to this, and will also help make it a bit more economical for your wallet.

    Friendly Green Oat Readigrass

    Oat grass is great for guinea pigs, as it contains a great amount of fibre and is tough to keep their teeth in check.

    It should primarily be used as more of a ‘treat’ hay, mixed in with their main Timothy or orchard grass. They should only have it in small amounts but it is appealing stuff, so be careful not to overfeed them as they will eat all they are given.

    The drying process from Friendly retains the goodness without the water, so it tastes fresh. Oat grass can also work out as a bit cheaper than other varieties, especially as it is only a treat option as opposed to the main bulk of their hay. With this purchase, you get 4kg overall, which is great value for the price.

    • Tasty to appeal


    • Size: 4 x 1kg

    Buying Guide

    Guinea Pig Diets

    Food for your guinea pig must always be suitable for that specific animal – pellets and nuggets for rabbits or other small animals should not be used.


    Like rabbits, roughage makes up the majority of their daily diets. They should always have some hay on, as it helps them to chew and grind down their teeth. Guinea pig teeth are always growing throughout their life, so they need something fibrous to gnaw on.

    It also contains fibre to help their digestive system moving. It can be surprising how much they eat, so keep everything topped up.

    A mix of timothy, orchard, and oat is best. Alfalfa contains too much calcium to be their main source of hay but is okay for an occasional treat


    Many owners will choose this as an easy option for the majority of their fresh greens intake, and keep the vegetables as a treat or supplements.

    Plain pellets, as opposed to mixed varieties, are best to avoid picky eating. The same applies to muesli, which can cause selective eating


    A large part of a guinea pig’s diet but most is often given in the form of pellets for ease. Around one teacupful of greens per day, such as green peppers, parsley, romaine lettuce and tomatoes, can give them some variety.

    Fruits such as watermelon, strawberries and bananas also act as greens, but these are like candy to a piggy so must be restricted to a slight piece once or twice per week!

    Mixed Food

    As mentioned above, plain pellets or nuggets are the best options for the majority of small animals as it prevents selective eating and means they don’t just pick out the tasty additions.

    But mixed food or muesli can be good for the occasional addition to your pigs daily food, as the alternative textures and tastes mean they don’t get bored.

    Just keep an eye and ensure they don’t just pick out the vegetable flakes and leave the rest.

    Vitamin C

    Guinea pigs can’t create or store this naturally so need a constant supply. This is why they need fresh veggies, and you must ensure pellets contain enough vitamin C for your pet.

    Other Buyers Ask...

    Why Is My Guinea Pig Eating Their Poo?

    This is completely natural! Guinea pigs have two types of poo – soft and hard pellets.

    The soft ones are packed with nutrients, from what your piggy has eaten but not digested. Eating this to make the most of the wasted nutrients is just what they do.

    The hard ones have already been digested once, though, so this is what you should remove from their cage.

    How Much Food Should I Give My Guinea Pigs Every Day?

    Ideally, you should give 30-50g of pellets per piggie per day. This is on top of a constant supply of hay and fresh water.

    It is therefore important to check how much you are buying before you purchase. A 1kg bag should do one average-sized pig for just under one month, so you may wish to set up repeat deliveries or set reminders if you will need to buy food regularly.

    They should have a continuous supply of as much hay as they want, and around a teacup of veggies per day as a vitamin boost.

    Does My Guinea Pig Need Water?

    Yes! All animals do. You should keep a  constant supply of fresh tap water in a glass or plastic bottle attached to their cage which they can reach.

    Clean this regularly and change the water daily to prevent bacteria build-up.

    Is There Anything My Guinea Pig Can’t Eat?

    Their stomachs are very sensitive, so even a slight bit of the wrong food can cause upsets. To be sure, only give them hay, pellets, and the approved fresh greens.

    Human food is pretty much out of the question, and they are herbivores, so don’t give them the dog’s leftover ham. Meat is actually poisonous for them.
