The best hay for rabbits is a good grass hay like timothy or orchard grass, and it should make up the bulk of what your rabbit eats every day. Adult rabbits need unlimited grass hay in front of them at all times, not a handful as a treat. Get the hay right and you head off two of the most common rabbit problems: overgrown teeth and a sluggish gut.
This guide walks through which hays work, which to skip for healthy adults, and how to judge quality by eye and nose. It’s written for New York homesteaders and small breeders who’d rather buy honest local hay than pay a premium for tiny bagged portions.
Why Rabbits Need So Much Grass Hay
Hay isn’t a side dish for a rabbit. It’s the main course. Grass hay should be roughly 80% of an adult rabbit’s diet, with pellets and fresh greens making up the rest. There are two big reasons for that.
First, teeth. A rabbit’s teeth grow continuously for its whole life. The steady chewing that hay demands wears those teeth down naturally. Without enough long-strand hay, teeth can overgrow and cause painful dental problems that often need a vet’s help.
Second, the gut. Rabbits rely on constant fiber to keep their digestive system moving. A diet short on hay can slow or stall the gut, which is a serious situation. The House Rabbit Society, a long-running rabbit welfare group, stresses unlimited grass hay as the foundation of a healthy rabbit diet. You can read their feeding basics at the House Rabbit Society.
So the simple rule: keep clean grass hay available around the clock, and let your rabbit eat as much as it wants.
The Best Hay for Rabbits: Timothy, Orchard Grass and Oat Hay
For healthy adult rabbits, you want a grass hay rather than a legume hay. These are the ones that keepers reach for most.
- Timothy hay — The go-to standard. It’s a good balance of fiber and coarseness, and most rabbits take to it readily. If you’re only going to stock one hay, this is the safe pick. Browse local timothy hay listings to compare cuttings and prices.
- Orchard grass hay — Soft, leafy, and sweet-smelling. It’s a great option for picky eaters or people who find timothy dust bothers their own allergies. See what’s available on our orchard grass hay page.
- Oat hay — A grassy hay with seed heads that many rabbits enjoy for variety. It works well mixed in with timothy or orchard rather than as the only hay.
Mixing two grass hays is fine and can keep a fussy rabbit interested. What matters most is that the base of the diet stays grass hay, offered without limit.
Why to Avoid Alfalfa for Healthy Adult Rabbits
Alfalfa gets recommended a lot, and that causes confusion. Alfalfa is a legume, not a grass, and it’s much richer — higher in calcium and protein than a grass hay. For a healthy adult rabbit, that’s usually too much.
The extra calcium is the main concern. In adult rabbits, a calcium-heavy diet is linked to bladder sludge and stones, which are painful and can be dangerous. For that reason, most adult rabbits do best on grass hay with little or no alfalfa.
There are exceptions. Alfalfa’s richness suits animals that are still building or feeding a body:
- Young, growing kits that need extra protein and calcium.
- Pregnant does carrying a litter.
- Nursing does feeding kits.
Even then, treat alfalfa as a life-stage tool, not a forever food, and shift to grass hay as young rabbits mature. Because these are health-sensitive situations, it’s worth confirming the plan with your vet. If you do need it for a litter or a nursing doe, our alfalfa hay section shows what local growers have.
How to Judge Hay Quality Before You Buy
Good rabbit hay is knowable by sight and smell, and you don’t need to be an expert to check it. Here’s what to look for.
- Color — Green is the sign of hay cut and cured well. A washed-out, yellow-brown bale has usually lost nutrition and appeal.
- Leafiness — You want plenty of leaf, not just coarse stems. Leaves are where much of the good stuff sits.
- Smell — Fresh grass hay smells sweet and grassy. A musty, sour, or “off” smell is a hard no.
- Dust and mold — Both are dealbreakers. Rabbits have sensitive respiratory systems, and dust alone can cause breathing trouble. Mold can make a rabbit seriously ill.
When you buy locally, you can open a bale, smell it, and run your hands through it before committing. That’s a real advantage over sight-unseen shipping. Ask the grower which cutting it is and when it was baled — an honest answer tells you a lot.
Buying Hay by the Bale for Multiple Rabbits
Small bagged hay from a pet store is convenient for one house rabbit. But if you keep several rabbits or run a small rabbitry, those little bags get expensive fast, and you’re paying mostly for packaging.
Buying a bale or two directly from a local NY grower usually works out far cheaper per pound, and the hay is often fresher because it hasn’t sat in a warehouse. A small square bale keeps well if you store it right, so it’s practical even for a handful of rabbits.
The trade-off is storage. Hay needs to stay dry and off the ground, or it’ll mold before you can use it — and moldy hay is exactly what you’re trying to avoid feeding. Our guide on how to store hay covers the basics of keeping a bale barn-fresh.

The Bottom Line on Feeding Rabbits Hay
Keep it simple: give adult rabbits unlimited grass hay — timothy, orchard grass, or oat — and make it roughly 80% of the diet. Save alfalfa for the young, pregnant, or nursing, and lean on your vet for those calls. Above all, feed hay that’s green, leafy, sweet-smelling, and free of dust and mold.
