  • 5 g carbohydrates
  • 3 g fiber
  • 9 g protein
  • 5 g fat

Can Guinea Pigs Have Corn?

Yes, guinea pigs can have corn. But they can only eat fresh, uncooked varieties, meaning that canned corn and corn products such as chips and tortillas are out of the question.

You can give a guinea pig fresh sweet corn, and they enjoy baby corn, too.

Can Guinea Pigs Have Corn Husks?

Yes! You can give a cavy corn husks as well as corn silk. Since corn is usually treated with chemicals, it’s important not to give your guinea pig the outer husks unless they’re from your own garden and you haven’t applied pesticides or herbicides.

Only offer the tender, lighter green inner husks that grow right next to the corn kernels.

If you give your cavy corn silk, take a similarly cautious approach and offer only the portions from deeper inside the husk. The outer corn silk or “tassel” could have traces of pesticide or herbicide on it.

Is Corn Good For Guinea Pigs?

Corn is really high in sugar, so it’s not the best thing for your guinea pig. At the same time, a little bit won’t harm them and they’ll benefit from the nutrients.

Corn husks are very good for your guinea pig. If you have fresh corn often, feel free to give your cavy corn husks as often as you like.

Do Guinea Pigs Like Corn?

Some guinea pigs like corn, while others prefer the corn husks only. The best way to determine if your cavy likes corn is to offer them a small amount and see how they react!

How Much Corn Can A Guinea Pig Eat?

That’s a great question and we’re glad you asked!

Here’s how much corn a to feed your guinea pig:

Age Amount
Baby guinea pig None
Adult guinea pig 1 tablespoon fresh corn kernels or 1 baby corn

That might not sound like much, but keep in mind, you can also give your guinea pig as many corn husks as they’ll eat.

Since corn is high in sugar, you’ll want to offer it on a different day than other sweet treats. Too much sugar can harm your guinea pig so it’s best to take a very cautious approach!

Keep an eye out for signs of discomfort or diarrhea since corn can sometimes cause digestive trouble. So long as everything is normal, you can keep giving your guinea pig fresh corn as an occasional treat.

How Often Can A Guinea Pig Eat Corn?

Because corn is so sweet, it really ought to be eaten just once per week or so. If you have fresh corn husks, feel free to offer them to your guinea pig as often as you like.

The Correct Diet is Important

A guinea pig’s natural diet doesn’t sound terribly interesting by human standards but for cavies, days spent nibbling on wild grasses and leafy plants are ideal! Your guinea pig will enjoy a healthier life if you try to mimic the cavy’s natural diet.

This means making Timothy hay a priority. Give your guinea pig an endless supply of fresh hay so they always have something to nibble. Not only does hay help prevent boredom, the fibers keep your guinea pig’s digestive tract running smoothly.

Besides an unlimited amount of fresh Timothy hay, here’s what to feed a guinea pig:

  • Guinea pig pellets fortified with vitamin C (Read the label to find the correct serving size as it varies by brand)
  • Fresh, clean water – Remember to rinse and refill your cavy’s water bottle every day
  • Approximately one cup of fresh food each day, preferably divided into two or three smaller servings; leafy greens and crunchy vegetables should be included

What Are Other Healthy Alternatives To Corn In A Guinea Pig’s Diet?

When fresh corn isn’t available and there are no corn husks to be found, you still have options! Guinea pigs love all sorts of veggies and fruits.

Here are some favorites to consider next time you’re searching for the ideal snack for your cavy.

  • cilantro
  • mint
  • basil
  • parsley
  • carrot
  • carrot tops
  • tomato
