But, beware, you cannot feed your pet just any type of mushroom. If you’re not sure of the type of mushrooms that you have, it is best to avoid feeding them to your pet piggy. It is certainly not worth the risk.
The only way you can treat your pet guinea pig with mushrooms is if you know what type of mushrooms you have. So, before you toss them as a treat to your pet piggy, make sure you know it’s safe for your pet.

When it comes to mushrooms being safe for your pet guinea pig, it depends on the type of mushroom you’re feeding your pet.
A good rule of thumb is to avoid feeding your pet mushrooms that grow in the wild. Those mushrooms are essentially poisonous and neither you nor your pet can have them.

Don’t worry, there are plenty of mushrooms that you can feed your pet piggy. These are usually cultivated mushrooms. Not only are they rich in flavors, but also rich in nutrients, and more importantly, free from toxins.
These include:
- White mushrooms
- Button mushrooms
- Portobello mushrooms
As long as you feed them raw and not cooked, there is nothing that can go wrong or make your pet sick. Your furry friend cannot eat or process cooked mushrooms which is why they should be avoided.
2) Do Mushrooms Turn Out Bad For Guinea Pigs?
You might find different answers on this that may contradict the other. However, you should know that mushrooms aren’t bad for guinea pigs. Just make sure you’re feeding your pet piggy the right type of mushrooms.
Interestingly, when mushrooms are sold in the market, they’re first tested on guinea pigs (don’t worry these don’t include the wild ones). So, if they were bad for guinea pigs, they wouldn’t be tested on them in the first place.

The best way to find out whether your pet enjoys mushrooms, there is only one way. Feed your pet a small serving and see if he or she wants it or shows interest in it.
If he or she eats it, well and good. However, if your pet doesn’t like the taste, don’t force them. There are plenty of other foods that you can feed your pet and mushrooms aren’t the end of the world.
