Learn how to pick the best hay for your rabbit or guinea pig, from timothy to alfalfa, with tips on freshness, storage, and feeding.
Hay is the foundation of a healthy diet for rabbits and guinea pigs. It provides essential fiber for digestion, helps wear down continuously growing teeth, and offers mental stimulation. But with so many options available, how do you know which hay is right for your small pet?
This guide breaks down the key factors to consider when choosing hay, including age, health needs, and quality indicators. Whether you're a new pet parent or looking to refine your current feeding routine, you'll find practical advice to make the best choice for your furry friend.
Why Hay Matters for Rabbits and Guinea Pigs
Rabbits and guinea pigs have sensitive digestive systems that require a constant supply of fiber. Hay provides the roughage needed to keep their gut moving and prevent issues like GI stasis. It also helps grind down their teeth, which grow continuously throughout their lives.
Beyond health, hay is a source of enrichment. Burying treats in hay or offering a Timothy Hay Roll - 3 Pack encourages natural foraging behaviors, keeping your pet active and engaged. A diet without adequate hay can lead to obesity, dental disease, and digestive problems.

- Offer unlimited fresh hay daily to adult rabbits and guinea pigs.
- Monitor hay intake; a sudden decrease could indicate illness.
Timothy Hay vs. Alfalfa: Which Is Best?
Timothy hay is the go-to choice for adult rabbits and guinea pigs. It is high in fiber and low in calcium and protein, making it ideal for maintaining digestive health and preventing urinary issues. Our 2nd Cutting Timothy Hay is soft, leafy, and fragrant, perfect for picky eaters.

Alfalfa hay, on the other hand, is richer in calcium and protein. It is suitable for young, growing animals (under 6 months) and pregnant or nursing females. However, feeding alfalfa to adult pets can lead to obesity and bladder stones. Use it as a treat or for specific life stages only.
- For adult pets, choose timothy hay over alfalfa for daily feeding.
- If you have young pets, you can mix alfalfa with timothy to ease the transition.
Other Hay Varieties to Consider
Orchard grass and meadow hay are excellent alternatives for pets with allergies or those who are picky. They offer similar fiber content and can be mixed with timothy to add variety. Brome hay is another option, though it can be harder to find.
When selecting a hay, look for a green color, a fresh, sweet smell, and a soft texture. Avoid hay that is brown, dusty, or moldy, as it can cause respiratory problems. Our 2nd Cutting Timothy Hay is harvested at the optimal time to ensure maximum nutrition and palatability.
- Rotate between different grass hays to keep meals interesting.
- Always check hay for signs of spoilage before feeding.
How to Choose Hay for Guinea Pigs Specifically
Guinea pigs have similar hay needs to rabbits, but they require a consistent source of vitamin C in their diet. While hay does not provide much vitamin C, it is still essential for their digestive and dental health. Pair high-quality hay with a vitamin C-rich pellet like Young Guinea Pig Food Pellet.
For guinea pigs, timothy hay is the best daily choice. Avoid alfalfa for adults unless recommended by a vet. Offering a variety of hays can prevent boredom and encourage eating. Remember, guinea pigs need hay available at all times, not just as a treat.
- Provide a constant supply of fresh hay in a hay rack or feeder.
- Monitor your guinea pig's hay consumption to ensure they are eating enough.
Practical Tips for Buying and Storing Hay
When buying hay, consider the packaging. Loose hay in bags can be easier to inspect, but compressed bales are often more economical. Our Timothy Hay Roll - 3 Pack offers convenience and freshness, with each roll designed to reduce waste and make feeding easier.
Store hay in a cool, dry place away from direct sunlight. Use a breathable container, like a paper bag or a dedicated hay bin, to prevent mold. Check hay regularly for moisture or pests. Proper storage ensures your hay stays fresh and appetizing for your pets.
- Buy hay in quantities you can use within a few weeks to maintain freshness.
- If you notice a musty smell or discoloration, discard the hay immediately.
Choosing the right hay for your rabbit or guinea pig is crucial for their health and happiness. Prioritize high-quality grass hays like timothy, avoid alfalfa for adults, and store hay properly to keep it fresh. By following these guidelines, you'll ensure your small pet thrives on a fiber-rich diet.
