Can Guinea Pigs Eat Lemons?

All guinea pig foods need to meet certain criteria. Dietary health, especially around the digestion, is pivotal to keeping small animals happy and healthy. Citrus fruits can help with this, as they are packed with Vitamin C – an essential part of any guinea pigs diet. Can guinea pigs eat lemons, though – and more to the point, should they eat such an acidic food?

Can Guinea Pigs Eat Citrus Fruit?

Acidic citrus fruits famously boast a high amount of vitamin C. As this is critical to the health of a guinea pig, citrus fruits can be a useful addition to the diet of a pocket pet.

It is not all good news, though. Citrus fruits should not be fed all the time, as there are certain risks to allowing guinea pigs to eat citrus fruits. As they are highly acidic, they need to be used sparingly in your guinea pig’s diet.

Let’s take a deeper dive into the relationship between guinea pigs and acidic citrus fruits – most notably lemons.

Do Guinea Pigs Like Lemons and Limes?

Small animals are generally low maintenance. However, when it comes to food, guinea pigs require very particular treatment. While nutritional value is critical in food, guinea pig treats and snacks also need to be appealing to the taste buds. Would a guinea pig even like the taste of citrus fruit?

This really depends on the guinea pig in question. It is no secret that lemons are highly acidic and bitter to the taste. This means that a guinea pig may reject the taste – and smell – outright. Even if the guinea pig gets past the initial bitterness, the acidic quality of lemons can be equal parts positive and problematic.

All the same, it is worth attempting to persevere and tempting a guinea pig to eat lemons – albeit just in small amounts. There are just as many benefits as drawbacks to letting your pocket pet enjoy citrus fruit.

Are Lemons are Good Food for Guinea Pigs?

Yes and no. On the one hand, lemons – like all acidic citrus fruits – are packed with Vitamin C. To keep healthy guinea pigs, food must contain this vitamin.

Lemons can also be used to manage the weight of a guinea pig. As they are acidic, lemons dissolve stubborn fats in a guinea pig’s stomach. What’s more, as lemons are so acidic, they will only be eaten in small amounts.

However, there are also bad points to lemons. The aforementioned acidic qualities, coupled high levels of sugar, phosphorus and calcium, make lemons a fruit to approach with caution. You’ll need to weigh up the pros and cons and decide whether to let guinea pigs eat lemons.

Advantages of Feeding Lemons to Guinea Pigs

So, you have decided to feed lemons to your guinea pig. Here’s why that’s a good idea.

  • Lemons are bursting with Vitamin C, which will stop your cavy from developing scurvy.
  • The acidic quality of lemons will dissolve any blockages or fats in your pet’s stomach.
  • Lemons have just the right amount of fiber for a guinea pig.
  • These fruits are low in fat, and thus comparatively low in calories too
  • Your pet will find plenty of antioxidants in citrus.

As you’ll see, once the acidic qualities of lemons are overcome, they can offer benefits to your pocket pet. As always, however, these are tempered by drawbacks.

Risks of Feeding Lemons to Guinea Pigs

We have used the word, “acidic” more times than we ever thought possible in this article. This quality is a good thing – but it can also pose problems.

Guinea pigs should never eat too much citrus. These acidic elements can cause stomach upsets if over-consumed, and lead to mouth sores for your cavy.

There are other risks to these fruits too. Lemons are:

  • High in sugar
  • High in calcium and phosphorus
  • Extremely bitter on the palate.

Do not force a guinea pig to consume lemons. It can source essential vitamins and antioxidants from other fruits and vegetables that are tastier on the palate. If your pet asks for lemons, though, they can be offered in very small, occasional doses.

Offering Lemons to Guinea Pigs

If you are going to allow your cavy to eat lemons, you need to understand how to serve these acidic fruits. You certainly cannot give a guinea pig lemons all the time, even if your pet does like the taste.

Acidic citrus fruits like lemons are best used very occasionally and under very particular circumstances. Never leave a whole fruit in your pet’s enclosure.

Can Guinea Pigs Eat Green Lemons?

A green lemon is not yet ripe. This means that it will be even more acidic than a yellow lemon. With this in mind, avoid feeding unripe lemons to your guinea pig. Until lemons turn a familiar shade of bright yellow, they should be left on the tree or in the fruit bowl. The green variety is too acidic for human digestion, let alone that of a small animal.

Can Guinea Pigs Eat Lemon Skin and Rind?

The skin and rind of lemons are just as nutritious as the flesh of the fruit. If your pocket petenjoys the taste of lemons, the skin can be consumed in moderation.

Just be aware that, while the skin contains all the goodness of the fruit, it’s just as acidic and sugary too. This can play havoc with a guinea pig’s digestion if you’re not careful.

Can Guinea Pigs Eat Lemon Seeds?

Seeds are invariably a choking hazard for a guinea pig, and those used to grow lemons are no exception. What’s more, the seeds found in lemons are particularly tough and hard to digest.

Even if your cavy manages to safely swallow the seeds, it may experience a stomach upset. Stick with the skin and flesh of lemons. Seeds may be less acidic, but they are actually more dangerous.

Should Guinea Pigs Drink Lemon Water?

Lemon water is often held up as a great drink for digestion and boosting metabolism due to the acidic qualities of the fruit. While this is technically true for small animals too, a guinea pig should only drink water infused with lemons in an emergency.

As discussed, lemon water is acidic. It’s also sugary, and not as hydrating as fresh tap water. Your cavy may like it, but use it extremely sparingly – if at all. Any kind of flavored water should only be used to tempt a stubborn guinea pig into drinking.


It’s a matter of debate as to whether guinea pigs should eat lemons. Cavy experts often cross swords on this subject, comparing the acidic qualities of lemons with the vitamins contained. The decision might be taken out of your hands; a cavy may refuse to eat lemons because they do not like the acidic taste. If your pet does like lemons though, they are worth offering from time to time.
