Many first-time guinea pig owners are surprised that their new pets need hay to thrive. In fact, about 80% of a guinea pig’s diet should be hay! That means they need to have access to an unlimited amount of fresh, clean, high-quality hay at all times. Why? Because it provides the fiber they need to maintain healthy digestion. Plus, it keeps their teeth, which grow continuously, from getting too long.
The best variety of hay for adult guinea pigs is Timothy. This type of grass is high in the fiber that guinea pigs need and low in protein and calcium. That’s important because piggies absorb about 50% of the calcium they ingest. (In comparison, humans only absorb 30%.) And too much calcium can lead to a variety of health issues, including bladder stones, hematuria, dysuria, metastatic calcification, and even death.
On occasion, you can feed your adult guinea pig other low-calcium hays like oat and orchard. But Timothy should be their staple hay.
Baby guinea pigs (pups), and pregnant and lactating females should eat alfalfa, which has the nutrition they need at that stage of life.
In addition to the variety of hay, you need to consider its quality, freshness, cut, dust level, lack of pesticides, and more. (See “Choosing the Best Hay: What to Look for” below.) If selecting the right hay for your guinea pigs is beginning to feel a bit daunting, don’t despair! Our experts have rounded up the best brands of Timothy hay and ranked them so you can pick the best hay for your guinea pig stress-free.

#1 Overall Best Hay: Oxbow Animal Health Western Timothy Hay
Our choice for the best overall hay for guinea pigs is Oxbow Animal Health Western Timothy Hay. Oxbow is the brand most recommended by – and used by – veterinarians. This nutritious, sweet-smelling hay is grown specifically for small pets in the U.S.A. by the company’s family of farms. It’s high in fiber to aid your pet’s dental and digestive health. It contains no additives or binders. And Oxbow’s hay growers limit the use of herbicides and pesticides to preserve crop integrity and product safety.
After it has been harvested, Oxbow’s hay experts gently separate hay strands from the bale. Next, they pick out any natural foreign materials and sort out smaller pieces. Finally, they extract as much dust as possible and sort the hay by hand.
The company, which has been providing premium hay for small animals for 30 years, is family-owned and operated. Their product quality team samples, grades, and tests their hay to ensure that it provides the nutrients your guinea pig needs. They also employ third-party nutritional and food safety testing.
Our tester guinea pigs, Ginger and Cocoa, preferred this brand to all others, giving it a resounding, “Wheek! Wheek!” It’s available in 15-oz, 40-oz., 90-oz, and 9-lb bags as well as 25-lb, and 50-lb boxes. We purchased it in 9-lb boxes because piggies eat a lot of hay. Every box smelled sweet and fresh, the strands were dark green and unbroken, and there was minimal dust.
2. Best First-Cut: Kaytee Timothy Hay 1st Cut
First-cut hay comes from the first hay harvest in the spring. Kaytee describes first-cut hay as being “more stemmy than leafy.” It also has an abundance of seed heads and tends to be more yellow and brown than green. It has higher fiber content and a lower protein and fat content than some other types of hay.
Nobody feeds more hay to small pets than Kaytee. Their first-cut hay is specifically grown for small animals without pesticides or artificial ingredients. After harvesting, Kaytee’s experts hand-select long, fiber-rich strands to ensure that they have the proper leaf-to-stem ratio that guinea pigs need for their dental and digestive health. It’s available in 6.5-lb bags.
For more than 150 years, Kaytee has been manufacturing nutritional foods for pet birds and small animals at its headquarters in Chilton, Wisconsin. They are so committed to keeping pets happy and healthy that they offer a money-back satisfaction guarantee.

4. Best Hay Cubes: Exotic Nutrition Timothy Hay Cubes
Hay cubes are a convenient, less-messy way to give your piggy the hay they need. These small, compressed blocks of sun-cured Timothy hay are intended to supplement conventional loose hay, not replace it. They’re particularly handy for when you’re traveling with your guinea pig. They also make an excellent low-fat, low-calcium treat. Because they’re compressed, they offer a more “challenging chew” than traditional hay, providing variety for your furry friend.
These Timothy Hay Cubes are made from compressed Timothy hay (40% minimum) and compressed alfalfa, which is used as an “adhesive” to hold the cubes together. They come in three-pound bags.
Exotic Nutrition has been family-owned and operated for 22 years. While they manufacture all of their pet foods in the U.S., this product was produced in Canada.
5. Best Hay for Babies (Pups): Small Pet Select Alfalfa Hay
Baby guinea pigs, which are called pups, have very different nutritional requirements than adults. That’s because their bodies are creating a foundation for a healthy life, including building strong teeth and bones. That’s why they need the extra calcium found in alfalfa hay instead of low-calcium Timothy hay until they’re six months old.
Pregnant and lactating adults can also benefit from eating alfalfa hay because their bodies need more calcium.
Alfalfa hay is an excellent source of protein, calcium, and other trace minerals. It also contains a wide variety of vitamins, including many of the B’s, C, D, E, and K, and the minerals phosphorus and zinc.
Our choice for the best hay for pups is Small Pet Select Alfalfa Hay. Unlike most companies, Small Pet Select hand-selects their hay from local fields in Washington’s Kittitas Valley. They hand-pack small batches in super-strong corrugated boxes. Then, prior to shipment, they recheck each box for quality. The result: Your piggy will receive the freshest, softest, most fragrant, sweetest tasting hay they’ve ever tasted.
This nutrient-rich alfalfa hay is available in 12-oz, 2-lb, 5-lb, 10-lb, 12-lb, 20-lb, 40-lb, and 50-lb easy open/easy close corrugated boxes. Plus, your piggy’s satisfaction is 100% guaranteed.
Choosing the Best Hay: What to Look for
When selecting the best variety of hay for your guinea pig, you should consider the following factors:
|Timothy Hay Quality Indicators||What You Should Know|
|Freshness||Fresh hay smells sweet when you open the bag or box for the first time|
|Cut||First-cut hay has firmer stalks and more seed heads. Second-cut hay is softer, less fibrous, and leafier.|
|Dust level||Dust refers to broken hay particles. No hay is completely dust-free, but premium companies take great care to make it as dust-free as possible since hay dust can cause respiratory problems in guinea pigs.|
|Lack of pesticides||Select hay that has not been sprayed with pesticides since they can cause serious illness in small animals that consume them.|
|Packaging||Most hay for small pets comes in bags or boxes. Bags are convenient because they are resealable. Boxes “breathe,” allowing|
|Price||Premium hay may be more, but it’s fresher, usually hand-selected, and contains fewer broken pieces, and dust.|
This review discussed two varieties of loose hay – Timothy and alfalfa – and compressed hay cubes. The pros and cons of each are as follows:
|Type of Hay||Pros||Cons|
|Timothy||Best for adult guinea pigs six months old or above due to low calcium content||Not suited for baby piggies (pups) because their developing bodies require more calcium|
|Alfalfa||Best for pups six months old or under and pregnant and lactating females due to high calcium content||Not suitable for adults except pregnant or lactating females because of its high calcium content|
|Compressed (Western Timothy) hay cubes||Cubes are a convenient, no-mess way to feed hay to your guinea pig when you travel. They also make a good treat because they’re more difficult to chew than loose hay.||They are designed to supplement the loose hay in your piggy’s diet, not replace it. Ounce-for-ounce, they are more expensive than loose hay.|
Users’ main complaints had to do with inconsistent or poor quality. One user stated, “My Guinea pigs always loved Oxbow, but I refuse to buy it now after finding so many horrible things inside of the bags. Things like giant dead bugs, rocks, and recently parts of what appears to be a dead bird. I have nightmares about what else could be in there that they might try and eat. Please try harder to fix this problem! I love this brand and I am disappointed that I can’t buy it anymore.”
Another said, “Very disappointed. I’ve been buying Oxbow Western Timothy Hay monthly for the past three years. The hay in this bag was dry and course and included dark dead hay. The hay was stiff, dry sticks which is great for bedding but we don’t buy it for bedding. My guinea pig can’t eat this stuff. I don’t know why the bags vary in quality so much but the past three bags have been awful.”
Most of the reviews from buyers were extremely positive, like this one: “Normally I don’t buy Oxbow, but my regular one was out of stock and my guinea pigs needed food. This was the same price. When I opened the bag, a very nice, sweet smell came out (a sign of freshness). My piggies immediately dove onto the portion I put into their pen. This is now my go-to hay. Also, as an added bonus, there is minimal dust in this bag. It feels good to know that I’m paying for the full product, not a product that is 1/4 dust.”
This reviewer raved, “There were two reasons I chose Small Pet Select Timothy Hay for my Guinea Pigs. First, I had tried many other different brands and was disappointed with them all. Second, I learned that they are a small family-owned business with a 100% money-back guarantee. The recyclable boxes are hand-packed with fresh, high-quality hay, beautiful and green. All of the other brands I have tried were low quality and very dusty. After ordering Small Pet Select, my piggies finally ate ALL of their hay, with no waste. Totally worth the money. They “wheek” so loudly for their hay now, they absolutely LOVE it. Thank you! Love, Chanel, Cookie, Linny, and Hamilton.”
The Best Hay for Guinea Pigs for 2022 FAQs (Frequently Asked Questions)
Do guinea pigs really need hay?
Yes! They need access to a continuous supply of fresh hay. These adorable herbivores eat hay for nutrition, to aid their digestion, and to keep their teeth from growing too long.
How often should I change my guinea pig’s hay?
Every day, you should remove any hay that your piggy has peed or pooped on and replace it with fresh hay. If you purchase a hay rack, it will keep your pet’s hay off the ground. Then you will only have to replenish the rack so it doesn’t run out of have.
What is “popcorning” in guinea pigs?
When a guinea pig is feeling super joyful or excited, it will spontaneously jump straight up horizontally. This is called popcorning because it’s reminiscent of a popcorn kernel popping
