The Best Timothy Hay for Rabbits

Rabbits evolved to graze on grass all day, and their teeth and digestive systems depend on it. Grass hay — timothy above all — should make up the vast majority of what your rabbit eats. Here is everything you need to choose it well.

Why Hay Is the #1 Rabbit Food

Grass hay should make up roughly 80% of a rabbit’s diet — it is the foundation everything else sits on. No pellet, vegetable, or treat comes close to its importance.

Dental health: a rabbit’s teeth grow continuously, and the long, tough fibers of hay grind them down as the rabbit chews. Without unlimited hay, teeth overgrow into painful spurs that require veterinary care.

Digestive health: hay’s fiber keeps the gut moving steadily, preventing the dangerous slowdowns that threaten rabbits. It also keeps them busy and content. In short, hay protects both ends of your rabbit — teeth and gut — which is why it must always be available.

Hay is not bedding and not a snack. It is 80% of the diet, the thing that keeps teeth worn and the gut moving. Never let it run out.

Why Timothy Hay Specifically?

Not all hay is equal. Timothy hay is the gold-standard grass hay for most adult rabbits.

• Ideal fiber balance. High in the long fiber rabbits need for teeth and gut health.
• Low in calcium and protein. Unlike alfalfa, it will not over-supply calcium that can cause urinary problems.
• Great for daily grazing. Its texture encourages the constant chewing that keeps rabbits healthy.
• Widely available. Easy to find in fresh, good-quality form for consistent feeding.

How to Judge Hay Quality

The difference between great and poor hay is easy to see, smell, and feel. Look for these signs of freshness.

• Green color. Fresh hay is green, not yellow or brown — green means more nutrients and appeal.
• Sweet, fresh smell. Good hay smells grassy and sweet; a musty or damp odor means avoid it.
• Long strands. Long, leafy strands are better than dusty, broken bits at the bottom of the bag.
• Low dust. Excess dust can irritate a rabbit’s sensitive respiratory system.
• No mold. Never feed hay with any sign of mold, damp, or clumping — it is dangerous.

How Much Hay Does a Rabbit Need?

The answer is beautifully simple: unlimited. Hay should never run out.

• Always available. Your rabbit should have constant access to fresh hay, day and night.
• A body-sized pile daily. A rough guide is a bundle of hay at least as big as your rabbit each day.
• Refresh often. Top up frequently so it stays fresh and appealing, not trampled or soiled.
• Free-feed, do not ration. Unlike pellets, hay is never limited — more is always better.

Other Hay Types (and When to Use Them)

Timothy is the staple, but a few other grass hays have their place.

Storing Hay to Keep It Fresh

Good hay can go stale or moldy if stored badly. Keep it fresh with a few habits.

1. Keep it dry. Store hay somewhere dry — moisture causes mold, which is dangerous.
2. Allow airflow. Use a breathable container or bag; sealed plastic can trap moisture.
3. Cool and dark. Avoid heat and direct sun, which fade color and nutrients.
4. Buy sensible amounts. Purchase quantities you will use before quality drops.
5. Check before feeding. Always glance and sniff for mold or damp before offering it.

Common Hay Mistakes (and Fixes)

Pro Tips for Great Hay Feeding

• Use a hay rack or box feeder. Clean, off-the-floor hay gets eaten far more.
• Encourage grazing. Put hay where your rabbit rests and toilets to boost intake.
• Buy in bulk carefully. Larger amounts are economical if you can store them dry.
• Rotate varieties. A little orchard or meadow hay keeps meals interesting.
• Watch intake as a health cue. A drop in hay eating is an early warning — call your vet.

Real-Life Example: The Power of Good Hay

A story vets and keepers see often: a rabbit fed mostly pellets with only a little dusty hay develops dental problems and soft, irregular droppings. On advice, the owner switches to unlimited fresh, green timothy hay in a clean rack, and cuts pellets back to a small daily portion.

Over the following weeks the rabbit chews constantly, its droppings firm up, and its teeth wear down naturally. The lesson experienced keepers repeat: unlimited quality grass hay is the single most important thing you can feed. When the hay is right, most diet-related dental and digestive problems fade — it truly is the foundation of rabbit health.
