Hey, are you looking for hay? You’ve come to the right place! This is where you’ll find the best hay for guinea pigs out there!

Choosing your little fella’s hay isn’t something you want to take lightly. Picking the wrong hay could lead to health problems.

To make matters easier for you, we’re going to guide you through finding the right hay and we’ll also give you some options!

Why Do Guinea Pigs Need Hay?

Guinea pigs need to have non-stop access to hay. Here’s a fun fact, guinea pigs’ teeth are always growing. 

Can you imagine that? This is where hay comes in, it’s like a chew toy, basically. Hay keeps the little fellas chewing To Wear Down Their Teeth so that they stay the average size and not overgrow.

It’s also essential to maintaining the bacteria in their intestines. In other words, it’s good for their digestive system.

Things To Consider When Buying Hay For Guinea Pigs

How can you know which hay to buy? This is what we’ll get into now. We’re going to tell you how to pick your hay, okay? Couldn’t help a little rhyme.

  • Type of Hay

First and foremost, you should see what kind of hay it is. Not all types of hay are safe for your little one. Timothy, Oat, Barley, And Grassy Hay are the kinds that are safe for your piglet.

Avoid feeding them clover hay and alfalfa. A lot of people promote alfalfa hay which is quite unhealthy for your little guy. Lucerne, or alfalfa, contains high levels of calcium, which Could Cause Stones and lead to surgical removal.

It would, however, be safe to feed them a mixture of alfalfa and other safe types of hay. Alfalfa is also rich in protein, which is why it could be used to feed pregnant or new mommies. The calcium and protein could give them a nutritious boost to help maintain their health.

  • Free of Chemicals

Chemicals can be fatal to any of us, let alone the little fellas. Pay very close attention to the hay you’re purchasing. Not all brands mention whether or not the hay is all-natural, which probably means it’s not! You should double-check that it’s free of chemicals to guarantee the well-being of your little one.

  • Quality

How can you know which hay is good and which is bad if you’re not the one eating it? You can put your other senses to use!

  • Sense Of Smell

When you open up the packet, take a good whiff of the hay. By the smell alone, you could tell if it’s fresh or old. It should smell sweet and strong.

  • Sense Of Touch

Now, put your hand in the hay. What does it feel like?

You want the hay to be as dry as possible. Moist hay is more likely to grow mold, mildew, or fungus pretty quickly and you don’t want your guinea pig to eat that.

  • Sense Of Sight

Take the straws out and look at them. Are they cut into little pieces or are they long strands? Short straws aren’t good for the digestive system and might even cause intestinal blockage.

  • Cutting

There are 3 different cuttings of hay.

First cutting is for animals who need a high fiber diet, especially those who need to shed a few pounds, no pun intended. It’s also recommended for animals with dental problems, believe it or not. It’s also low in calcium and protein.

Second cutting hay is ideal for everyone. All of the nutrients are perfectly balanced so it’s good for all ages. 

Does your guinea pig refuse to eat hay? Is it elderly or recovering from something? Try third cutting hay! It’s softer than the others, which makes it easy to chew for guinea pigs with health problems. It could also be used to help them put on some weight. 

Third cutting hay is typically rich in protein and calcium and low in fiber. You don’t want to use it frequently unless instructed otherwise by a vet.

How Much Hay Should I Give My Guinea Pig?

As much as he/she desires! 80 – 90% Of A Guinea Pig’s Daily Diet should consist of hay. No matter what else you feed it, it can’t replace hay. You’re going to need it to be available for your little piggy all-day-long, every day!

The question of how much depends on how much your buddy can chomp down in one day. If you’re looking for an average, you’re probably looking at 1 oz a day.

Here are some questions other guinea pig guardians are asking.

  • What should I do if my guinea pig refuses to eat hay?

If your guinea pig won’t eat his/her hay, try different types. It’s probably because that particular type isn’t appealing to him/her. Chances are it probably isn’t fresh or could be moldy.

Try one of our top picks and check the hay yourself before giving it to the little guy. Make sure it’s fresh-smelling, dry, and that the strands are long.

Make sure to supply your guinea pig with fresh hay and not leftovers. Hay grows mold pretty quickly, it could explain why he/she refuses to eat it.

Place the hay somewhere where it’s not close to any water, otherwise it’ll go bad in no time.

  • Do I need to throw out any hay that is left after 24 hours?

Yes. Hay can grow mold pretty quickly so you need to change it pretty quickly. 

  • How often should I change my guinea pigs’ hay?

You should change your guinea pig’s hay no less than once a day. Otherwise, you could risk it going bad and harming the little guy.

  • Can my guinea pig have fresh grass instead of hay?

While grass is quite healthy for guinea pigs, if it’s in certain conditions, it’s Not Sufficient To Fully Replace Hay. You could feed your guinea pig some grass beside hay, but don’t fully rely on it.
