  • Lemons Are Not A Healthy Choice For Guinea Pigs

The lemons are densely packed with beneficial nutrients, but still, guinea pigs cannot eat them. There are serious lemon-related health issues for guinea pigs. A few of them are mentioned below. 

  • Fibers, Sugars, And Digestive System Risks

Guinea pig’s digestive system is not as developed to bear fiber and sugars. When they encounter unnecessary sugars and fibers, the digestive system is unable to break out these compounds. Lemon is composed of such sugars and fiber, which leads to loose stools, feeling bloated, stomach discomfort, growth of bacteria in the stomach, and more. 

  • Calcium-Phosphorus And Urinary Tract Problems

The presence of phosphorus and calcium traces develops urinary tract problems in guinea pigs. Excessive calcium, when stored in the body, causes kidney stones and bladder stones. The pain of kidney and bladder stones is unbearable, and if not treated on time, can lead to death. On top of that, the calcium-phosphorus ratio can foster urinary infections. Due to this, the urinary tract unexpectedly develops issues like blood in the urine. 

Can Guinea Pigs Have Lemon Juice?

No, lemon juice is just like poison to a guinea pig’s stomach. Lemon juice is too acidic that will disturb the performance of the digestive system. This will result in tummy trouble. Lemon squash is as harmful as the lemon juice itself. It contains ample sugars so it matters if you add water to make it dilute. It will still not be recommended for guinea pigs. Guinea pigs can only drink water instead of juices or squash.

Lemon being too acidic, is not preferred for guinea pigs. If you put a lemon in front of them, they will not like to eat it at all. However, if you wanted to give it a try, cut a thin portion and give it to the piggies. Guinea pigs can eat lemon fruit twice or thrice a year. 

Like the whole lemon, lemon peels could be served in a tiny bit quantity. Although lemon peels have a saturation of Vitamin C, it is still not acceptable. 

Can Guinea Pigs Eat Green Lemons?

Not at all, you cannot think of feeding green lemons to guinea pigs. Whether green or yellow lemons, they are the same. The difference is between their PH level and color. Green lemons have a high PH value of 2. Green lemons are far more dangerous when compared with yellow lemons. With the PH 2, acidity in lemons turned high. 

Can Guinea Pigs Eat Yellow Lemons?

Yes, they can have yellow lemons in very strict proportions yearly. When the green ones lay aside for a few days they automatically started turning into yellow lemons. When a lemon changes its color, PH also starts changing. In yellow-colored lemons, the PH number counts for 3. No matter, the PH level is 2 or 3, it will always be harmful to the guinea pigs’ health. 


Lemons either yellow or green are not meant for guinea pigs. They are unfitted to have lemon as in daily or weekly treats. Their delicate digestive system can handle too much acidic fruit. Lemon intake in guinea pigs causes underlying issues like mouth sores, teeth grinding, and more. Lemons are rich in vitamin C, but you can find other alternatives to fill the gap.
