Risks to Consider When Feeding Apples to Guinea Pigs

Generally, apples are quite safe and healthy fruits for both human and animal consumption. However, some studies have shown a few risks that come with the use of apples. Although they are not so severe, it is worth knowing what they are. The following are some of the content deemed risky in apples:

  • Although not a significant issue per se, apples are quite sweet fruits, and so they add sugar to the body when consumed. Too much sugar is harmful and therefore should be regulated if possible. However, sugar is still vital to the body, and a little of it or controlled bits would be necessary. That is why you would need to know just how much enough for your guinea pig is.


  • Seeds that are found inside the apple fruit contain a powerful poison known as cyanide. Eating too many of these seeds can pose a potential risk for your guinea pig. To avoid this, you can perhaps eat the fruit without the grains. Make sure you get rid of the seeds before eating.


  • This is another factor about apples. They are slightly acidic, and this can be harmful if taken in too many bits. When feeding your guinea pig with apples, be sure to give it just enough and not too much of it. This acidity, when in plenty, can be quite harmful to your pet.

Too much of anything is harmful, and this is something that you need to have in mind even when feeding your guinea pig with apples. Regulate the number of apples that you give so that they are neither too many or little.

If the sugar is too high, your guinea pig might suffer health complications and in some cases even gain unnecessary weight.

Well, not much danger can occur in this case except that you will notice the guinea pig bloating or slightly having diarrhea.
