Guinea pigs can drink water, but can they drink tea?

No, guinea pigs cannot drink tea, because some teas contain caffeine, which is harmful to their health. In addition to caffeine, some teas also contain additional ingredients such as artificial colors and artificial sweeteners, which are also harmful to guinea pigs.

Tea does not have enough vitamins that guinea pigs need, especially vitamins A and C which are of great importance to our pets.

In today’s article, you will learn why tea should not be given to guinea pigs, as well as other questions related to this topic.

Why shouldn’t tea be given to guinea pigs?

Tea is not a good drink for guinea pigs because it contains caffeine, and theobromine and does not have enough nutrients that they need to improve their health.

Here’s a more detailed explanation of why we shouldn’t give tea to our furry friends.


Teas contain theobromine, which is very similar to caffeine and can cause diarrhea and nausea in guinea pigs.

Theobromine will make the guinea pigs feel very sick and start to behave strangely, making strange noises as a sign that something is wrong with them.

Theobromine can also cause expansion of their blood vessels, which in the worst case can cause bleeding of some organs in our pets.

Lack of vitamins

The teas do not contain enough vitamins that the guinea pig needs to be healthy. Tea lacks essential vitamins A and C, which are most important for guinea pigs.

Vitamin A deficiency causes guinea pigs to have weaker immunity which will reduce their resistance to disease.

Guinea pigs have to get vitamin C in their body through their diet, lack of vitamin C causes scurvy and other health problems.

Unknown herbs

When we make tea, we cannot be aware of the composition of various herbs and plants that may contain harmful ingredients for guinea pigs, such as:

  • oregano
  • ginger
  • rosemary

Even if the tea does not have some of these herbs it can still be harmful to guinea pigs because of the way it is processed.

Artificial colors and sweeteners

Apart from the danger of various herbs and plants used for tea, we must also mention artificial colors and sweeteners.

They can be toxic, high in sugar, and cause illnesses such as diarrhea in guinea pigs.

We, humans, have a different digestive system than guinea pigs and can handle some of the harmful ingredients in tea, but guinea pigs and their soft and delicate digestive systems will have major problems.


Caffeine is one of the most common ingredients in tea that is very harmful to guinea pigs. If guinea pigs drink caffeinated tea they risk diarrhea, dehydration, and frequent urination.

Also, caffeine creates problems for the metabolism of guinea pigs and calcium in their organism.

Caffeine is difficult for the digestive system of guinea pigs to digest and under no circumstances should it be introduced into their bodies.can guinea pigs drink tea
