The simple answer is yes, guinea pigs can eat cauliflower! However there are some important things to consider before you decide to introduce them into your piggy’s diet. There are many health benefits, as well as a few drawbacks to weigh in!

We've also got a Vegetable Master List that lists common veggies that your piggy can and can't eat!

What vitamins and other nutrients does cauliflower contain?

Vitamin C

This vitamin is essential in any guinea pig’s diet in order to combat the onset of scurvy and boost their immune system, which will help fight off illnesses! This is especially important when it comes to fighting off infections that guinea pigs are so susceptible to. These infections can be extremely dangerous if untreated, but we want to prevent that by making sure they don’t catch them in the first place! Vitamin C also prevents scurvy, which makes it difficult for guinea pigs to eat. Cauliflower contains 46.4mg in a 100 g portion. 

Vitamin K

Vitamin K helps with blood clotting, which will make a huge difference if your piggy ever gets injured! It’s important that their blood is able to clot, because if your guinea pig happens to catch a fungal infection, their wounds that occur from these need to be able to scab so their bodies are able to begin the cell regeneration process and help them heal! Cauliflower contains 15.5 µg per 100 g portion. 


This is important for your guinea pigs to consume because it helps maintain their digestive system! Eliminating wastes from the body is important for overall healthy body function. Making sure that your guinea pig’s digestive system is regular is important because guinea pigs eat their own poop!

This process is done because the first time they eat their food, they aren’t able to fully absorb all the nutrients. The second time around, they’re able to extract the rest. You’ll rarely see them do this though, as they usually eat it as soon as it pops out.

What other benefits does cauliflower provide for your guinea pig?

Cauliflower is low in sugar content, so it won’t contribute to the development of diabetes or obesity! In guinea pigs, obesity can be a concern because that leads to even more health concerns. Cauliflower also contains omega fats, which can contribute to a soft, shiny guinea pig coat! It can also help prevent the onset of osteoarthritis, which can be common in older guinea pigs.

Cauliflower is also another one of those veggies that is rich in water! It’s super good for contributing to keeping your piggy hydrated.

What are the downsides about cauliflower for guinea pigs?

The calcium and phosphorus content in cauliflower can be a cause for concern when it comes to adding it to your guinea pig’s diet. It’s important to moderate the amount of calcium in their diet so they don’t develop bladder stones! That being said, too much cauliflower can make the amount of calcium problematic.

There’s also a matter of the presence of pesticides on the cauliflower you buy. In general the veggie is susceptible to damage from insects when it’s being grown, which means a large amount of pesticides is used to prevent that. Consumption of these pesticides can render your guinea pig very ill, so it’s important to thoroughly wash the vegetable before you feed it to them.

Gas and bloating can also occur, so it’s important if you choose to include it into their diet that you keep an eye on their waste output! This can be the best way to gauge whether the amount you’re giving them is too much and you should reduce it, or if you should stop completely.

Guinea pigs can eat cauliflower, but do they like it?

They do! However, it seems that they tend to like the leaves better than the florets themselves.

How should you go about feeding your guinea pig cauliflower?

The most important thing about preparing cauliflower for your guinea pig is to make sure you wash it well so you can get rid of any remaining pesticides! You can serve your piggy a half-inch floret or a single leaf of cauliflower first to see how they respond. If it goes well and their excrement isn’t affected negatively, it’s safe to transition into giving them a full portion, which is a one-inch floret. However, you should still limit this treat to once or twice a week!

Overall, it is OK to feed your guinea pigs cauliflower!

It’s important to keep in mind that cauliflower is a healthy treat that can only be enjoyed once or twice a week in order to ensure that your guinea pig stays safe and healthy! Make sure to pay close attention to how they respond in order to gauge what is best for them.
