If you set guinea pig’s cage outside your home, this technique can also help.

For those who are trying to use cedar or wood shavings to keep them warm, I will recommend not doing that. Those are not only poor insulation options but also harmful for piggy’s lungs. Instead of that, Use fresh hay or go for fleece bedding.

9. Work well for a litter training

Hay is used in the litter box or tray to litter train the piggies.

What are the drawbacks of using hay as bedding?

Despite various advantages, hay bedding has a lot of disadvantages. That’s why people go for some special bedding options for guinea pigs.

Here are the cons of hay as bedding.

1. Poor odor control

As hay gets wet and can’t be dried so easily, it will produce a bad smell like a barn. So, it may not be friendly for the owner.

2. Guinea pigs pee on hay

If your guinea pigs aren’t litter trained, they will pee on it frequently. So, all cages can be dirty and wet very soon.

3. Not a good absorbent

Hay isn’t very good absorbent. Moreover, guinea pigs will pee on it again and again and keep it wet all the time, if they’re not little trained. So, it’s a bad option as bedding to maintain hygiene. Even though many of you would like to use newspaper as an absorbent, it might not work well in a long run. Besides, the ink of newspaper bad for piggies health if they decide to eat that.

4. Mold quickly

Hay bedding gets mold so fast because of poor absorbency and pee of your piggies.

5. Growing up of bacteria and microorganisms

Since guinea pigs pee on hay bedding and it remains wet all the time, bacteria and microorganisms can be grown up very easily which’s bad for piggy’s health.

6. Need frequent cleaning

To maintain proper hygiene and keep the bedding free from moisture, you have to change the hay bedding quite frequently than other bedding materials. You have to replace the bedding every 2-3 days with new hays. But, still, all of the drawbacks make it a bad option for bedding.

Which hay is better for guinea pig bedding?

Fresh meadow hay is a great option for guinea pig’s bedding for temporary use. This hay is soft and comfortable as for them. Moreover, they also get nutrition from the meadow hay. However, you must put timothy or orchard hay as the main diet inside the cage.

However, make sure that meadow hay is fresh and doesn’t contain any dust.

Can you use timothy hay for guinea pig bedding?

Timothy hay can be used as bedding for guinea pigs. The good thing about fresh timothy hay is it has a pleasant smell and can absorb some moisture. Besides guinea pigs love to nest in it and eat it whenever they want. However, the downside is timothy hay can’t control odor, mold fast, and need to change frequently.

Absorbancy isn’t so good as other bedding options. When timothy hay gets wet, it will mold fast.

You can use ink-less paper under the hay to increase absorbency.

How can use hay in a guinea pig’s cage?

First of all, buy good quality hay that’s not dried. Dried hay isn’t suitable for guinea pig’s bedding. So, you should get hay from a farmer.

Most of the hay that you get from a pet store is dried. So, it makes a poor bedding option.

Moreover, you can purchase it from the farm supply store at a much less price.

Now, if you have decided to use hay as bedding for guinea pigs, you should be aware of its drawbacks and take some important actions.

Hay isn’t very good absorbent. So, use shredded paper or newspaper on the floor of the cage and then put hay over it. This will keep the surface dry and prevent bad odor. Make sure that paper is inkless or it can be harmful to piggies. But, truth is, even using a paper layer can’t prevent moisture and odor much.

Besides, you must remove any soiled material regularly from the surface.

Within 5 days hay starts to composts. So, this bedding can’t even last more than 3 days and it will start to mold and grow up bacterias because of the pee that remains on the hay.

So, you have to change the hay every 2-3 days or earlier to prevent microorganisms from growing and keep your guinea pigs healthy.

However, all of these are hard to do and it makes a wrong choice as a bedding option. So, I suggest you choose another bedding option for your guinea pigs.

Hay vs Straw for guinea pigs bedding

Many people get confused between hay and straw. These two are completely different when we talk about pets. Hay is soft and friendly for pets such as guinea pigs while straw is hard and doesn’t make comfortable bedding for guinea pigs. The sharp structure of the Straw can injury the eyes, ear, nose, and different parts of your piggies body. In addition, straw can’t absorb urine or moisture and make the surface wet. This makes it unhygienic bedding. Moreover, it can’t control odor. So, straw is not recommended as bedding for guinea pigs.
