Why Is Hay Important for Guinea Pigs?

Why Is Hay Important for Guinea Pigs

When cavies were running around in the wild, they always had grass, sticks, and other things to chew on. That’s just what guinea pigs do. Now, when cavies have been domesticated, it is all up to you what your beloved pet would be getting on a daily basis.

Hay contains a lot of fiber. Fiber is extremely important for digestion. It will help keep the digestive tract of your animal moving which will help in avoiding a lot of health problems.

Hay does not only provide the guinea pigs with important fiber. With the help of hay that cavies like to nibble on, their teeth will wear down. If you are planning to adopt a guinea pig, you should already know by now that the teeth of these rodents continue to grow throughout their whole life.

In case they have nothing to chew, the teeth will start to overgrow. Such a situation can cause a lot of inconveniences, as well as appear to be fatal in the end. Simply assuming that the small portions of food that you give to your guinea pig should be enough to help it wear its teeth down is wrong. The cage of your fluffy ball should be full of fresh hay at all times. But that’s not the only major advantage of hay.

When using hay, keep this in mind:

Even though the hay that you’re going to be giving to your guinea pig should be high in fiber, it shouldn’t have a lot of calories, calcium, and protein. Only pregnant, nursing guinea pigs or the cavies that are recovering from illness might need more of those things. However, you should always consult your vet.

On a daily basis, calories can make your guinea pig become too fat. And as cavies can’t regulate the levels of calcium and protein in their bodies, their excess might cause bladder stones to appear. That’s also an unpleasant condition that can lead to a lot of dangerous complications.

Types of Guinea Pig Hay

Bear in mind that there are two main groups of hay out there:

Legume Hay

Legume Hay

Legume hay is high in calcium, protein, calories and doesn’t have a lot of fibers. If your dear animal is recovering from an illness it might need those extra calories. As well as calcium and protein. Pregnant and lactating sows need these things to ensure that their babies have enough biological material to build a healthy body. Moreover, young cavies may also need more protein.

However, sometimes owners decide to give legume hay to their guinea pig to simply provide a bit of variety. Give legume hay to healthy, grown-up guinea pigs in moderation. Though grass hay certainly is a better option for them.

Alfalfa and clover hay are the two most popular types of legume hay.

Grass Hay

Grass Hay

The hay of choice for adult guinea pigs is usually grass hay. This type has a lot of fiber and nutrients that are essential for your pet’s teeth and overall health.

Just like with legume hay there are different types of grass hay. For example, oat hay, orchard grass, Bermuda grass, Timothy hay.

Timothy Hay

The majority of owners prefer Timothy hay as it’s the most widely available option. But bear in mind that not only the type of hay affects the quality. It is also important to know when the hay was harvested. Let’s take Timothy hay as an example.

In the stores, you can find the first, second, and third cutting of the Timothy Hay. The reason why the farmers do that is pretty obvious. The majority of them want to try and get as much money as they possibly can from their crops. That’s why they try and grow as much hay as they can during the season.

  • First cutting – It is extremely rich in fiber.
  • Second cutting – Guinea pigs tend to prefer the second cutting as the stems are a bit softer, thus more pleasant to chew on.
  • Third cutting – Considered to be the most delicious one for our cavies, but, unfortunately, it doesn’t have enough fiber in it. So you can choose to add the third cutting as a treat, rather than a constant supply.

Where Can We Store Out Hay?

Where Can We Store Out Hay

Proper storage is extremely important as it will help you preserve the hay fresh and full of all the necessary nutrients. The room where you keep the hay should be well ventilated, cool, dark, and dry. Better put a cover of some sort on the hay, so that there is no dust, but make sure that the air can still circulate. If stored properly, hay can be preserved for around a year.
