Hay

Importance
Hay is the most important part of a rabbit's diet. It is the prime source of fiber to keep his GI tract working properly and also helps grind down their teeth to prevent overgrowth. Hay can also serve as entertainment, as it takes a while to chew. Some bunnies like digging and rearranging their hay.

One may think that pellets are sufficient, but pellets have been developed to be an easy comprehensive diet for meat and show rabbits and is not necessarily good for the rabbits in the long-term. Pellets do have a fiber analysis of around 20%, but natural hay offers around 30%, as seen below. Additionally, pellets offer many more calories than natural hay, and if fed too much, can lead to obesity. Rabbits can never eat enough hay and will not gain weight on an unlimited proper hay diet.

Types
There are many types of hay available on the market, however, rabbits should only be consuming either alfalfa, a legume hay, when young or grass hays when older. Additionally, if you decide to buy by the bale, make sure the hay is horse quality, not cow quality, because horses have comparable sensitivity to rabbits while cows are more tolerant.

Some hays will also come with a choice of first, second, or third cuttings. The links below provide more information on what this means.

Alfalfa
Alfalfa is a legume hay, not a grass hay. It is high-fiber like grass hay but also contains more protein, energy and calcium. As a result, alfalfa should only be fed to growing young bunnies under the age of 7 months. For the older bunny, constant alfalfa hay consumption can lead to gummy droppings, weight gain, sludge, and cecal pellets not being eaten.

Alfalfa is typically distinguished by their usually brittle stalks with flat green to brown leaves. Hay can vary from dark lime-green to yellow, green, or brown depending on the season.

Timothy
Timothy hay is the most popular hay fed to rabbits. It looks like a dried fairly wide blade of grass, and its color is a soft green to grey or brown-green. Timothy hay also has "solid cattails" which distinguishes it from Orchard grass which has "broken cattails."

Oat Hay
The San Diego House Rabbit Society states, "If bun's diet is high in oat hay, the pellets she produces will be larger, lighter in color, and will look like sawdust if crushed. Many bunnies would benefit from eating more oat hay, an excellent preventative for GI Stasis."

Other Hay

Grass Hays

Legume Hays

Miscellaneous Hays

Straw
Straw is the dried stalks of cereal plants like wheat and a by-product of harvest. If any seeds remain on the stalks, it is by accident. Hay refers to grasses or legume plants cut down fresh and baled for animal feed. Hay bales are usually greener than straw bales, and the plant material finer.

Although rabbits eat it, straw is not recommended because it is low in nutrients and will lead to deficiencies if it is a major part of the diet. However, straw can be safely used as a bedding, especially for outdoor hutches during the winter.

Pet Store
Pet stores will carry a variety of hay (i.e. Timothy, orchard grass, alfalfa, etc.). Typically, the amount that can be bought will range from about 24 oz up to 5 pounds. Although it is convenient to buy hay at a local pet store, this is often an expensive option. A 64oz bag will usually last a couple of weeks at ~$8. Additionally, most pet store brands offer lower quality hay that is very hard and stalky. The recommended popular hay brand is Oxbow, although this may be quite expensive since they carry a premium price compared to other commercial brands.

Some brands may offer fruit mixed in the hay -- DO NOT BUY THESE. Fruit is not necessary for a rabbit and contains a lot of sugar. If your rabbit does not seem to be eating his hay (which is a giant problem), cut down on other sources of his diet (i.e. vegetables, pellets, and treats). If he has no source of food but the hay in his living space, he will consume the hay. Only buy bags of hay with only hay in them and no other treats. Dried herbs are acceptable, however. You can feed fresh healthy treats on the side, independent of the hay and easily rationed.

Through the Local Rabbit Rescue
If you live in a location with a House Rabbit Society chapter or rescue, check and see if they sell boxes, flakes, or bales of hay at a cheap price! Of course, buying a bale yourself will be cheaper, but if you do not have the space to store it, support your local HRS chapter or rescue! They will most likely sell fresh hay at a better rate than the small bags at pet stores. Your bunny will most likely love and wallow in the fresh hay.

Some examples of House Rabbit Society chapters and rescues that sell hay include the following:
 * San Diego House Rabbit Society, San Diego, CA -- $12 for 10-12lbs of hay
 * House Rabbit Society Headquarters, Richmond, CA -- $5 for a flake (garbage bag full) of hay

Online in Bulk
Some bunny owners like buying their hay online in bulk. These suppliers also typically ship much fresher hay than the average commercial brand.

The following is a list of reputable online retailers in the US:
 * American Pet Diner
 * Bingaling Bunnybox Store
 * BunnyBale
 * BunnyBytes
 * BunnyLuv
 * FarmerDave
 * KMS Hayloft
 * Sierra Valley Pet Hay
 * Small Pet Select
 * Sweet Meadow

By the Bale
The cheapest option typically is a bale of hay. One bale, usually ranging from ~70 to 110 lbs depending on type, can feed one rabbit for approximately a year. However, this requires space to properly store the hay as it is easily perishable when wet.

You can obtain a bale of hay at local animal feed stores, select rabbit rescues, or farms. Be sure that if you purchase from a feed store or farm, the hay is horse-quality, not cow-quality. Cows have much more tolerant stomachs while horses are comparable to rabbits.

See Hay Bale for more details on how to split and store hay.

Craigslist Ads and Word of Mouth
Sometimes, you may be able to find private owners that wish to share a purchased bale of hay to make it more manageable. You may be able to get great deals this way. Look for owners of rabbit or guinea pigs as they have similar hay requirements.

How to Store Hay
It is very important to keep hay dry and out of direct sunlight. Dampness will cause mold in the hay, and sunlight may leech out nutrients in the hay over time. The best location to store hay is in a cool indoor location out of direct sunlight.

If you must store hay outside, invest in a waterproof tarp along with some bricks to keep the hay off the ground to prevent mold.

Dispensing Hay
There are many options available to dispense hay to your rabbits. Some owners directly place a layer of hay in the litter box. Other use hay racks to minimize the amount of waste from pee and poop soiling. Commercially made hay racks can be easily found in pet stores and online.

Not Eating Enough Hay
Rabbits need to have most of their diet consist of hay. If your rabbit does not seem to be eating that much, there is a problem.
