Can Guinea Pigs Eat Styrofoam? All You Need To Know

Guinea pigs often eat what they should and what they shouldn’t. That’s why you have to take care and pay attention to them when they eat so that they don’t eat something that could cause problems with their health.

I did some research on whether guinea pigs can eat styrofoam as my guinea pig ate a small amount, and here is what I found out on this topic.

Can guinea pigs eat styrofoam?

Guinea pigs can eat styrofoam, but in small amounts to make it safe for them. As long as they don’t have problems with pooping and peeing eating styrofoam won’t be a problem for them.

In any case, they should never eat often or in large quantities because it can block their digestive system and cause health problems.

In today’s article, you will find out whether guinea pigs can eat styrofoam and whether it has bad effects on their health.

Can guinea pigs eat styrofoam?

Guinea pigs can eat styrofoam, you just have to be careful not to eat too much because then it can cause certain problems with the digestive system.

Styrofoam is mainly harmless to guinea pigs because it is made of polystyrene, which is a material that does not break down in the guinea pig’s stomach.

In any case, styrofoam also contains certain chemicals that, when reacted with heat and acids, can cause a certain reaction in the guinea pigs’ bodies.

Those chemicals are:

  • styrene
  • diethylhexyl adipate

Small amounts of these two chemicals will not pose a problem for your pet.

If guinea pigs eat more styrofoam and ingest more of these two chemicals then problems with their digestive system can occur.

To know if everything is fine with your guinea pig after eating styrofoam, it’s enough just to watch if it pees and poops regularly.

If you notice that he has problems when he needs to go to the toilet or if he has certain pains, then you should immediately consult a veterinarian.

Styrofoam can also cause problems for guinea pigs in other ways, through other chemicals or dyes that come into contact with the styrofoam.

If, for example, styrofoam was used to pack food, then the guinea pig could be poisoned.

Although Styrofoam is not toxic, it all depends on what it was used for before it ended up in your pet’s stomach.

In any case, if you notice any problems with your guinea pig after eating styrofoam, you must take him to a veterinarian to examine him and see if there are any more serious health problems.

How can styrofoam negatively affect the digestive system of guinea pigs?

As we said, a larger amount of styrofoam can cause certain problems with the digestive system of guinea pigs.

A larger amount of styrofoam can cause blockages in your pet’s stomach, esophagus, and intestines, which is a serious problem for their health.

Sometimes this problem has to be solved by surgery to remove the blockage, so they should not be allowed to eat too much styrofoam.

Any operation is dangerous for small animals, so it is best to avoid this situation for your pet.

What should I do if the guinea pig eats styrofoam?

If your guinea pig has eaten styrofoam you should not panic, first, you should wait and see if everything is okay with his pooping and peeing.

If you notice unusual changes when he goes to the toilet then you should take him to the vet immediately for an examination.

It is best to always watch what the guinea pig eats because prevention always prevents problems with their health.can guinea pigs eat styrofoam
