Can Guinea Pigs Eat Limes?

Limes are a vibrant-green fruit with a bright green flesh, acidic lemon taste, and specific aroma. And it is like a green lemon, with just a few minor differences. We use limes for cooking and cocktails mostly, because it’s healthy and tasty too. But, is this fruit good for the guinea pigs? Let’s see below.

Can guinea pigs eat limes? No, guinea pigs can’t eat limes. This fruit is acidic, but it has some sugar and it is sweeter than a lemon. Because of these things, lime can’t be given to guinea pigs. The digestive tract of cavies is not meant for digesting lots of sugars. Also, the stomach of guinea pigs might become upset from the high acidity of this fruit.

Maybe our guinea pigs don’t drink Mojitos, but this doesn’t mean they shouldn’t try lime! Even if the cavy doesn’t like the taste, at least it would try it and there is no harm in that. However, if you decide to feed your guinea pig lime just for the taste, you should see more details them in the sections below.

Health Benefits of Guinea Pigs Eating Limes

  • Energy – lime has carbs and proteins, which are the main sources of energy. When the cavy gets the needed carbs, it will have the energy right away. From the proteins, the guinea pig will have energy that lasts long after the digestion is over.


  • Good digestion – this fruit has fibers too, and it’s a known fact that fibers improve the digestion and work up the stomach too. Just be careful with the serving size; too much fiber might upset the stomach, but a normal amount in moderation is ok.


  • Antioxidants – vitamin A in lime has many functions. Primarily, it is an antioxidant and the job of antioxidants is to protect the body from diseases and from free radical damage. Without antioxidants, immunity is compromised, and there are more diseases. But, vitamin A acts as a shield against health problems and it improves the immunity overall.


  • Prevention from scurvy – the best thing about limes is that they have lots of vitamin C. Guinea pigs can’t produce this vitamin themselves, so fruits or veggies that have vitamin C are the best things you can feed your furry pet with. Scurvy is a dangerous disease that manifests with rough coat, discharge, internal bleeding, no appetite, weight loss, and fatigue.


  • Prevention of muscle aches and electrolyte balance – limes have potassium and this mineral brings lots of benefits. Primarily, it soothes aching muscles. This means all muscles will be relieved from aches – this includes the heart muscle too. With potassium, there is also a balance between the salts (electrolytes) and water in the body.

Nutrition Facts of Limes

Per one lime (2 oz), there is:

  • Carbs and proteins – 7 g carbs and 0.5 g protein. The carbs give instant energy, and the proteins release energy slower after digestion, and this energy lasts longer too.


  • Fiber – There is 1.9 g in one lime. The fibers are needed for healthy digestion. The fibers don’t just improve digestion, but they also reduce any risk of heart diseases and diabetes too.


  • Vitamin A – 1% vitamin A. This vitamin helps with the formation of bone tissue and teeth. Also, this vitamin is an antioxidant and keeps the overall immunity in great shape. White blood cells are formed with this vitamin as well.


  • Vitamin C – there is 32% vitamin C. Guinea pigs need this vitamin because without it, they get scurvy. Sadly, guinea pigs can’t produce vitamin C by themselves, but luckily, lime has this vitamin.


  • Potassium – 68 mg of potassium. This nutrient keeps all muscle tissues pain-free. There are fewer aches in the body, the muscles hurt less, and the heart muscle is kept in good shape too. Also, potassium regulates the blood sugar and it keeps the balance between water and electrolytes.

Risks to Consider When Feeding Limes to Guinea Pigs

The major risk that comes with lime is calcium content. This mineral is crucial for forming strong bones, but it can also cause health problems in cavies. One lime (2 oz) has 22 mg calcium! This amount is quite high for the guinea pigs. They can’t consume too much calcium once they are fully grown and developed. Calcium is needed while the pups are growing up, but older guinea pigs don’t need it that much.

When there is an excess of calcium, this mineral deposits in the urinary tract of the guinea pig. Then calcium can cause bladder or kidney stones, painful urination, or even blood in the urine. Consult the veterinarian if you notice these symptoms in your guinea pig. If left untreated, this can worsen and can lead to renal failure, which is fatal.

Another risk is the sugar content. Limes are sweeter than lemons, and they have 1 g of sugar per fruit. This is not so scary because the guinea pig cannot consume a whole lime at once, even if it wants to. However, if you give the guinea pig lime, do it occasionally and in small amounts, and the guinea pig will be fine.

Quick Facts on Limes

  • The lime originates from Southeast Asia.
  • The most popular lime types are: Persian, West Indian, dessert lime, sweet lime, kaffir lime, and key lime
  • Lime is cultivated all year round, and the best limes are picked from May to September.
  • In the 19th century, the disease scurvy spread mostly among sailors. In that period of time, lemons used to be quite pricey, so the lime was the ‘lemon alternative’. Every British sailor was advised to consume a whole lime every day to avoid the scurvy.
  • The greatest lime manufacturer worldwide is India
  • Arab traders used to travel across Asia in the 10th century, so when they discovered lime, they brought the trees back to North Africa and Egypt
  • In Europe, limes were introduced in the 12th and 13th century, and this was done by the traveling Crusaders
  • Christopher Columbus brought lime seeds to the West, on his way back home, during his voyage in 1493. Soon after that, limes were commercially sold in Florida, Mexico, and the West Indies.
  • The word ‘lime’ comes from the Persian word ‘limu’.

How much lime can the guinea pig eat?

You can slice the lime, and after that give just one tiny piece to the guinea pig. This should be enough for the cavy to taste it because more than one small chunk will be too much. Lime is very acidic, just like the lemon, and this can disturb the stomach of the guinea pig. You can give this to the guinea pig, but just for them to taste it.

What happens if the guinea pig eats too much lime?

No need to panic if the guinea pig had an extra bite of the lime chunk. But, the expected side effects are upset stomach and intestines. Make sure there is other fresh food in the cage, as well as fresh water – this will suppress the side effects of too much lime and will soothe the stomach. Basically, it is impossible for a guinea pig to eat a whole lime fruit because of the acidic taste, so no worries!
