#Stomach Pain

Stomach Pain is one of the common issues with acidic foods. Hamsters are small in size, so a small amount of acid can harm them a lot. As it is advised not to serve any citrus fruits to your hamsters like Orange, Pineapple, and others, it would also be great if you stay away from other acidic fruits as well.

Although a tiny amount might not cause anything, serving a lot can harm your hamster. Furthersome, serving it frequently can also harm their stomach in the long term.


Acidic fruits help digestion for humans, but they can also harm small pets like hamsters. Consuming acidic contents can make your hamster poop frequently and cause diarrhea.

It can also affect your hamsters’ bowel movements, worsening the situation.

Also, the seeds of the Guava are hard to digest; thus, if you serve this fruit, make sure you remove them.

#Other Issues

  • Allergy
  • Constipation

What Will Happen If Your Hamster Eats Guava?

If they eat it in tiny amounts, don’t worry; your hamster will be safe. But, if they have eaten in large amounts, then make sure you check your hamster frequently, especially the poop, and if you see any problem make sure you contact a VET.

Hamsters might like guava because of its sweetness, but as I told you, long-term it can harm them.
