Can Guinea Pigs Eat Asparagus? What You Need to Know!

Eating our greens is easier when there’s a side of asparagus at the table. It’s just so delicious, and healthy too! But can guinea pigs partake in the fun?

Yes! Guinea pigs can eat asparagus. Asparagus is not toxic to your furry buddies and can be a healthy addition to their diet when given in small amounts.

A word of caution: feeding your guinea pig too much asparagus can increase their risk of bladder stones. Very small portions (a couple of slices of a spear) once or twice a week is the most we think is wise.

For further considerations on the health benefits of asparagus and why you should be cautious and careful when feeding it to your guinea pig, read on!


About Asparagus and Fun Facts

Asparagus is an herbaceous plant that has been enjoyed by humans for thousands of years. Though nowadays, the mention of asparagus brings to mind the strong scent it can give our urine, it has a long history as an aphrodisiac and medicinal food.

We only eat young asparagus, or the shoots. Once the plant grows large enough, it ends up branching out and looking more like a fern or tree – and though woody stalks may sound appetizing to a guinea pig, they are far too fibrous for people.

The most common color of asparagus in American grocery stores is the bright green variety, but there are also white and purple asparagus. And guinea pigs can eat all three!

Health Benefits of Asparagus for Guinea Pigs

In small amounts, asparagus can nourish your guinea pig in a number of ways.


These versatile nutrients are beneficial to your guinea pig’s general health in a variety of ways. Antioxidants can boost the immune system and help prevent urinary tract infections and colds. And asparagus has tons!

Antioxidants protect cells from dangerous oxidative stress and free radicals, both of which contribute to premature aging and inflammation.


Also known as vitamin B9, folate is an essential nutrient that helps make red blood cells, as well as convert carbohydrates into usable energy.

Vitamin A

Asparagus is rich in vitamin A, which supports many functions throughout the body. Vitamin A contributes to the development of skin and tissues, as well as eyesight. It supports the health of multiple organs including the liver, the heart, and the lungs.

Vitamin C

Similar to humans, guinea pigs cannot synthesize their own vitamin C in their bodies. That’s right, just like pirates and sailors guinea pigs also have to worry about getting scurvy!

While asparagus does contain vitamin C, it has smaller amounts than many fruits and veggies. So, it needs to be part of a well-balanced diet and not the sole source of this vitamin.

Vitamin K

Vitamin K helps your guinea pig’s blood clot when they have a cut or injury and contributes to the healing process. And asparagus has tons of this essential nutrient!

The best part about getting more vitamin K in your piggy’s diet is that it also helps regulate calcium in the blood. Excessive calcium can contribute to bladder stones – a painful and sometimes dangerous condition that is common in guinea pigs with a poor diet.

Can Asparagus Be Bad for Guinea Pigs?

There are also quite a few health concerns you should know about before you add asparagus to your guinea pig’s diet. Moderation is the key here!

Bladder Stones

One of the biggest reasons you should limit the amount of asparagus you give your guinea pig is that asparagus contains oxalic acid. Oxalic acid can cause bladder stones, or the crystallization of calcium in the urinary tract that is incredibly painful to pass.

Guinea pigs are already prone to bladder stones, so they need extra caution when it comes to asparagus. As an occasional treat, asparagus can be fine, but don’t include it as a regular staple of their diet.


Small herbivores like guinea pigs are incredibly sensitive to pesticides. These common chemicals can be toxic, upset a guinea pig’s stomach, and even lower their immune system.

Choose organic asparagus types over non-organic, and you won’t have to worry about pesticides. And be sure to thoroughly wash any vegetable you give your piggy.

Digestive Upset

Depending on your guinea pig’s constitution, large amounts of asparagus can cause problems for their belly. Bloating and gas, constipation, or diarrhea are all common effects of too much asparagus.

To avoid issues like this, it is always best to introduce new foods to your piggy slowly and cautiously. See how they react to a small amount first. Do you notice any lethargy or irregular bowel movements? If so, asparagus may not be a good option for your furry friend.

How to Feed Asparagus to Your Guinea Pig

Asparagus should be served to your guinea pig cleaned and totally raw. And your little piggy can eat any part of the asparagus, from stalk to tip and everything in between!

Never feed your guinea pig cooked or seasoned food. Their gastrointestinal system is not designed for cooked foods and they cannot digest it.

How Much Asparagus Should I Feed My Guinea Pig?

A few small slices no more than twice a week will suffice. Don’t go overboard, even if your guinea pig ends up loving asparagus.

It may be hard to say no to those pleading eyes and happy squeaks, but moderation is critical. Eating excessive amounts of asparagus can increase your guinea pig’s likelihood of developing bladder stones. Proceed with caution and care for your fuzzy little friends!

Final Thoughts on Feeding Asparagus to Your Guinea Pigs

So, can guinea pigs eat asparagus? Yes, any color. Feel free to share a couple of small slices of fresh, clean asparagus with your guinea pigs.

However, while this herbaceous vegetable is not toxic for guinea pigs it is also inadvisable to feed in excess. Due to the oxalic acid in asparagus, you should not feed your little piggy asparagus regularly or in large amounts. No matter how much they squeal!

Happy munching!
