Why do Guinea pigs need to eat so much hay?
On top of the benefits of grass hay on your Guinea Pig’s tummy, it is also important in maintaining dental health.
A Guinea Pig’s rear teeth grow continuously, so constant grazing and chewing on grass hay wears these down and prevents them from becoming too long and uncomfortable.
Grass hay is naturally quite abrasive, so makes the perfect material to for him continuously chomp, chew and grind down those rear teeth. It’s super tasty too!

Types of Hay
Timothy Hay
Timothy is naturally abundant throughout Europe and America and is named after the farmer who supposedly introduced the species to North America, Timothy Hanson.
It is commonly used for cattle feed and small animal feed due to its long fiber content and abrasiveness. As mentioned above, these are both great for the animal’s health and well-being.

Some other common names which you might hear are ‘Cats tails’ or ‘common cats’ tails’ because of the appearance of the flower, which is said to look like a cat’s tail! This is not to be confused with the ‘meadow fox tail’, which tends to flower earlier in the year.
An interesting fact is that the pollen of the Timothy hay family is an allergen, and has been used to develop anti-histamines, which are used to treat hay fever!

Alfalfa Hay
Alfalfa is a perennial plant from the legume family. Legumes are plants that are solely harvested for their dried seeds. Some of the other seeds in the legume family regularly harvested for human consumption are Peanuts, Chickpeas, and lentils.
Alfalfa Hay, therefore, is not grass hay, but legume hay. This is an important point to note since legume hays are much higher in calcium, protein, and carbohydrates than grass hay, and can cause bladder stones if fed in high quantities to your Adult Guinea Pig.
Limit your Adult Guinea Pigs Alfalfa hay intake by reserving for treats and occasional use.
It is, however, recommended to blend in some Alfalfa hay with grass hay for younger Guinea Pigs, or pregnant sows, as the need for increased levels of calcium and protein during these periods is important for the growth and rearing of young pups.

Hay Quality
Hay makes up a large percentage of the Guinea Pig’s diet. Therefore, it is important to supply your Pet with the best possible quality hay, with the greatest nutritional value possible.
There are several things to look out for with regards to Hay Quality, and ensuring your pet is getting the very best.
- Hay Stem Diameter. A Smaller diameter stem indicates the hay was harvested earlier, and therefore contains more nutrients.
- Fewer flowers and seeds. This again indicates a less mature Hay, which will be richer in Nutrients than an older Hay
- Hay Color. Hay should be bright green with a little fading. Anything yellow or black is likely to of been stored for too long, or in poor conditions and would have lost all of its Vitamin content.
- Hay Cleanliness. Your hay should contain just that! anything else including dust and dirt indicates the hay hasn’t been harvested or stored adequately.
- Hay Smell. Hay should smell fresh and appetizing! If there are any signs of mold or muskiness, then it’s likely your piggy will not be overly interested in eating it and worse case could cause health problems.

Fresh Grass
Fresh Grass is an excellent addition to your Guinea Pig’s diet as it contains a high level of vitamin C. Be sure that the grass is not treated with any herbicide or pesticide first, as this can cause serious health issues.
If you have a safe grassy area in your backyard, then let your Guinea pig search for a forage itself which adds some fun and exercise as well as a nutritional snack!
