5 Best Timothy Hay for Guinea Pigs

We’ll start with something not all people know…

Guinea pigs are rodents which means their teeth are always growing.

For both that and dietary reasons, the most important item in the cage is hay, which the guinea pig should always have access to. Here’s why:

  • The teeth in the back of the mouth of a guinea pig are ground down through the silica in grass and hay
  • Guinea pigs like to chew on hay all day long
  • Guinea pigs can quickly become ill if they do not have access to hay
  • For that reason, your guinea pig should always have access to hay
  • Hay should make up approximately 80% of the daily food intake

Now, the million-dollar question becomes: What kind of hay should you feed your guinea pig?

  • The short answer is a type of hay called Timothy hay
  • The slightly longer answer is to feed more alfalfa hay when they are up to four months of age as this contains more calcium, and then switch to timothy hay afterward
  • Also, if your guinea pig is pregnant it should be fed alfalfa hay

In addition, you need to feed your guinea pig hay that is soft and more grass-like as compared to stiff hay that is more straw-like.

With these considerations in mind, as well as “how much the guinea pigs like the different types of hay”, we have found the three best options below when it comes to guinea pig hay.

#1 Small Pet Select 3rd Cutting “Super Soft” Timothy Hay Pet Food

Grass hay should be available to guinea pigs at all times. It provides them with fiber to keep their digestive system healthy and helps grind their teeth to prevent them from growing too much.

Timothy hay is the best and most recommended hay, especially to adult guinea pigs. It contains just enough calcium so you won’t have to worry that about your pet developing stones.

The Third Cutting Super Soft Timothy Hay from Small Pet Select is contained less stem and seed than the second cutting. It is the company’s softest timothy hay that even the pickiest eaters will start to enjoy eating hay.

Hay with this kind of quality is rare and is difficult to find. Like what the company says, it’s a “gift” from Mother Nature. Not a given.

We love not just the product, but also the company that sells it. They pride themselves on proving that they want the best for our pets by creating small batches of their product to make sure that only the finest products are delivered to us.

Key Features
Has more leaf, less stem, and seed
Super-soft hay that is rare and difficult to find
Produced in small batches to make sure that fresh hay is delivered

#2 Small Pet Select 1st Cutting “High Fiber” Timothy Hay Pet Food

Just like the first item on the list, this one is also from Small Pet Select.

This is the First cutting of Timothy Hay and has a more flower head and pliable stem which means that it has a higher fiber content than any other cutting.

Like what was mentioned earlier, Small Pet Select proves their genuine care for our little pets by providing only the best timothy hay.

Their products are hand-selected to find the highest quality products to deliver to you. That is why, their hay is difficult to find because as they say, hays are not created equally and what matters is the quality.

Many guinea pig owners love the products from small pet selection. A lot of them say that their pets go crazy for it and it is the only hay that made them actually eat hay.

Key Features
Has a high fiber content having more flower head
Hand-selected to find the best product

#3 Kaytee Wafer Cut Hay 60 Ounces

This Timothy hay from Kaytee is all-natural and is in wafer cut. The wafer cut is supposed to peel off in layers to make feeding easier and to lessen the mess.

Kaytee timothy hay is hand-selected as well to make sure that long fiber strands are selected and that there is a proper leaf to stem ratio to support the health of the guinea pigs’ digestive system.

The hays from Kaytee are grown from an ideal ecological setting to control moisture and climate and then stored in a protected environment where their quality, freshness, and nutritional value can be maintained.

Basically, all the timothy hay offers the same quality and nutritional value. The only difference is the location and way on how they were grown and harvested.

For this product, one of its differences is its cut which many guinea pig owners say is very helpful in keeping the mess under control.

Key Features
The wafer cut makes feeding easier and minimizes mess
All-natural and chemical-free
Grown from an ideal location and stored in a protected environment

#4 Thunder Acres Premium Alfalfa Hay for Pets

 As we all should know, Alfafa hay has a higher calcium content than Timothy hay and is best to be given to pregnant, nursing, and growing guinea pigs aged 6 months below to help with development.

With adult guinea pigs, it should be served as a treat because daily intake of alfalfa might cause them kidney stones.

The Thunder Acres Premium Alfafa Hay was grown in the plains of Kansas. It was sun-cured and is free of weed.

Your pet will definitely have more on their plates and will be chewing a lot because this alfalfa was hand-packed to make sure that it will not be damaged and will retain more leaves.

There are a lot of positive reviews about this hay being fresh, fragrant, and green. However, you should always be cautious and set your expectations because after all, this is a plant-based food and is prone to spoil in a short period.

Key Features
Grown in the plains of Kansas
Sun-cured and weed-free
Hand-packed and contains more leaves

#5 Oxbow Animal Health Alfalfa Hay

The Oxbow Animal Health Alfafa, like all the other hay in this list, is also hand-picked to ensure that only the best strands of hay are put into every bag that we purchase. It is free from chemical additives and preservatives.

One dilemma that guinea pig owners have is how to store the excess hay properly. Fortunately, Oxbow’s alfalfa is packed in a convenient, mess-free, and resealable bag to make storing easier and to help the hay extend its lifespan.

However, you must keep in mind that storing hay for too long might spoil. So, it is recommended that you only buy how much you need.

Unfortunately, there are more negative than positive reviews for this product. Most of the negative mentions that it is full of dust and half of the bag contains practically dust.

So, it may be better to buy this type of product at the pet store to make a better judgment of their quality.

Key Features
No added preservatives
Hand-picked to ensure high-quality
Packaged in a convenient mess-free and resalable bag

What Are the Characteristics of Good Guinea Pig Hay?

When selecting hay for your guinea pig, it can be a jungle to figure out: What are the characteristics of good guinea pig hay?

There are quite a few things that good guinea pig hay have in common which are:

  • Should be very leafy, soft and pliable with a grass-like structure
  • Should be a natural green and not the yellow color of full-grown wheat
  • Smell clean without any smell of dust, burns or mold
  • Naturally be free of any trash, dirt, weeds or other unwelcome material

When getting guinea pig hay, you should go for something that is not the first cut. The first cut generally refers to the first harvest after winter and this hay is usually stiffer and less desirable than the second or third cutting.

Alfalfa Hay for Guinea Pigs

When getting hay for your guinea pig you should always be getting timothy hay unless you can answer yes to one of the following:

  • Your guinea pig is pregnant
  • Your guinea pig is below the age of 4 months

If you can answer yes to any of those, you should feed your guinea pig a mixture of 50% timothy hay and 50% alfalfa hay.

There are a couple of reasons why you need alfalfa hay:

  • Contains more calcium which pregnant and growing guinea pigs need more of
  • Helps their digestion

There is not the same amount of choice when it comes to alfalfa hay on the market, but the hay below is a favorite when you need alfalfa hay for your piggy.

A Balanced Guinea Pig Diet

The secret to a good guinea pig diet is balanced meals and here is the full breakdown of the recommended daily diet for your pig:

  • Approximately 80% timothy hay
  • 10-15% snacks such as vegetables and fresh herbs. Shoot for the equivalent of 1 cup-full, which will weigh ~2oz (50 grams)
  • 5-10% pellets of guinea pig food. One eight of a cup or a little less than an ounce is all they need. If they are fast growing pigs up to the age of 4-6 months, you can double this ratio.

Finally, it’s worth pointing out that it’s a very good idea to get a hay rack for your guinea pigs.
