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

Can guinea pigs eat asparagus? Yes! Though asparagus is pretty pricey at the market, plenty of pet parents feed their cavies the trimmed stalks they would otherwise throw away. Nutritious and completely safe for guinea pigs, this is a great way to widen your piggy’s diet and provide a bit of variety.

Asparagus is safe to offer your guinea pig regularly in amounts up to ¼ cup.

For those that are interested, we’ll take a closer look at why and how guinea pigs can eat asparagus and consider the pros and cons.

Is Asparagus Good For Guinea Pigs?


Guinea pigs rely on a varied, healthy diet to supply the vitamins and minerals they need. And in addition to unlimited Timothy hay and fortified pellets, they need a full cup of vegetables every day to ensure that they get the nutrition required to keep them in top shape.

While leafy greens like arugula, chard, and parsley should pretty much always be on the menu, variety is good, and asparagus can be a fantastic addition to the daily “salad” you offer your cavy.

Asparagus is loaded with Vitamins A, B6, and C, and it’s also a great source of iron, magnesium, potassium, and fiber. Naturally low in sugar, it does contain a bit of calcium, but without oxalates to bind with, we wouldn’t worry about that.

The bottom line? There’s nothing in asparagus that you need to worry about, and it’s a great source of the vitamins and minerals for your guinea pig’s health demands.

Is Asparagus Bad For Guinea Pigs?


The main things to watch for when selecting fresh foods other than Timothy hay are sugar, oxalates, calcium, and water content. It’s also wise to keep an eye on toxins (we’re looking at you, green parts of the tomato!) and choking hazards.

Asparagus is very low in sugar, which constitutes just 1.9% of its mass. That’s almost nothing, and given that guinea pigs are prone to obesity and diabetes, asparagus really shines here.

It does contain a small dose of calcium, but no oxalates for that mineral to bind with, vastly reducing the risk of bladder and kidney stones. You shouldn’t worry about this veggie unless your guinea pig has a proven track-record of bladder or kidney issues.

Some veggies, like tomato and cucumber, are very high in water, and while that can help keep your cavy hydrated, in larger amounts, it can also cause diarrhea and tummy troubles. No worries here when it comes to asparagus!

And finally, asparagus doesn’t contain any toxins, so you don’t need to worry that you’re feeding your furry friend the wrong part of the plant. It’s also one of the least contaminated veggies, so pesticides aren’t much of a risk.

That’s all good news!

How Should You Prepare Asparagus For Your Guinea Pigs?

Asparagus is easy to prepare, and since it’s also one of the least contaminated veggies in the market, you don’t really need to go to much trouble before serving it to your cavy.

When you’re preparing asparagus for yourself, many people break the stalks by hand to separate the woody ends from the tender stalks. If you’re not familiar with what we mean, it’s really easy.

As Faith Durand explains, “Simply take the end of the asparagus between your thumb and forefinger and bend until it breaks. Lest you think we are belaboring such an obvious point, let us say that the fun in this is that the asparagus automatically breaks just where the woody part ends and the fresh, juicy asparagus begins. So you don’t need to worry about breaking off too much or too little.”

Those woody bits are ideal for your cavy, and most guinea pigs will happily munch on those crunchy ends.

So the next time you’re cooking asparagus, save some for your furry friend!

And of course, never feed your guinea pig cooked or canned asparagus. Fresh only!

How Much Asparagus Should a Guinea Pig Eat?

Asparagus is completely safe for guinea pigs, but it shouldn’t replace leafy greens. That’s not likely given its relative cost, but we thought we should mention it.

A thoughtful guideline is that you shouldn’t offer your pet more than about ¼ cup of asparagus a day.

  • It’s also low in pesticide contamination.
  • Guinea pigs can safely eat asparagus frequently, but we wouldn’t recommend any veggies but leafy greens be offered every day.
