Nutritious and Delicious: A Guide to Oat Hay for Chinchillas

Chinchillas are herbivores, and they require a diet that’s high in fiber to maintain good digestive health. Along with a balanced diet of pellets and fresh water, hay is an essential component of their diet. While timothy hay is the most commonly available option, oat hay can also be a viable option. In this article, we’ll take a closer look at oat hay and whether it’s a good choice for your chinchilla.

What is Oat Hay?

Oat hay is a type of grass hay that is harvested from the oat plant. Unlike other hays that are cut and then left to dry, oat hay is typically harvested when the oat plants are still green and growing. This can result in a hay that’s greener and softer than other types of grass hays.

Benefits of Feeding Oat Hay to Chinchillas

Oat hay is a good source of fiber, which is essential for maintaining good digestive health in chinchillas. It also has a higher protein content than timothy hay, which can be beneficial for chinchillas that need extra protein in their diet. Oat hay is also lower in calcium than other hays, which can be beneficial for chinchillas that are prone to bladder stones.

Drawbacks of Feeding Oat Hay to Chinchillas

One potential drawback of oat hay is that it can be higher in fat content than other hays. This can be a concern for chinchillas that are prone to obesity or other health issues related to a high-fat diet. Additionally, oat hay can be more expensive than other types of hay.

How to Choose Oat Hay for Your Chinchilla

When selecting oat hay for your chinchilla, look for hay that is green and free from dust or mold. Avoid hay that looks brown or yellow, as this can be a sign that it’s old or has been exposed to moisture. You should also look for hay that has a soft texture, as this can be easier for your chinchilla to chew and digest.

How to Store Your Chinchilla’s Oat Hay

Oat hay should be stored in a cool, dry place to prevent mold growth. You can store it in a hay rack or bin that’s specifically designed for storing hay. It’s important to check the hay regularly to make sure it hasn’t become damp or moldy.

Nutritional Breakdown of Oat Hay

Oat hay has a nutritional content that’s similar to other grass hays, with a few key differences. Here’s a breakdown of the nutritional content of oat hay:

  • Fat: 1-2%

Oat hay is a good source of fiber, which helps to maintain good digestive health in chinchillas. It’s also higher in protein than some other types of hay, making it a good choice for chinchillas that need extra protein in their diet. Additionally, oat hay is lower in calcium than some other hays, which can be beneficial for chinchillas that are prone to bladder stones.


Oat hay can be a good alternative to timothy hay for chinchillas, especially if your chinchilla needs extra protein in their diet or is prone to bladder stones. However, it’s important to be mindful of the higher fat content in oat hay, and to select high-quality hay that’s free from dust and mold. With the right care and attention, oat hay can be a healthy and nutritious addition to your chinchilla’s diet.
