To find out how oat milk affects your cat and which types of oat milk are safe, read on!

Is Oat Milk Safe for Cats?

Oat milk is a plant-based milk, and some plant-based foods can be safe and even beneficial for them in moderation.

But remember that too much oat milk can damage a cat's digestive system, regardless of its nutritional value.

What is the Nutritional Value Oat Milk Contains?

Oat milk is made by soaking oats in water and blending them, resulting in a creamy and lactose-free beverage. While it may be a suitable alternative for humans, it lacks several essential nutrients that cats need to maintain optimal health. But don't be discouraged if your cat drinks oat milk regularly, they will also get essential nutrients

Vitamins and Minerals

Oat milk is often fortified with various vitamins and minerals to enhance its nutritional value. Common fortifications include vitamin D, calcium, vitamin B12, and sometimes iron. Vitamin D helps regulate calcium and phosphorus levels in the body, which are essential for cats' bone health. Vitamin B12 plays a vital role in various bodily functions, including cats' red blood cell production, nervous system health, and metabolism.


Oats are a good source of dietary fiber, and some of that fiber carries over into oat milk. A cup of oat milk may contain approximately 2-3 grams of dietary fiber. Adequate fiber intake helps maintain a healthy digestive system and can prevent or alleviate certain gastrointestinal issues in cats, such as preventing constipation in cats, helping regulate blood sugar levels in cats with diabetes and hairball prevention.

What Kind of Milk is Safe for Cats?

Many adult cats suffer from lactose intolerance, which means that they lack the lactase enzyme needed to properly digest lactose (the sugar contained in milk), so it is generally recommended to avoid feeding regular milk to cats.

If you want to provide milk-like treats for your cat, there are specially formulated "cat milk" products available in pet stores. These cat milk alternatives are typically lactose-free or have reduced lactose content, making them easier for cats to digest. They are designed to mimic the flavor of milk without the lactose, so cats can enjoy them without experiencing digestive issues.

Can Cats Drink Ooat Milk As a Treat?

Of course, As above. For lactose intolerant cats, consuming milk or dairy products can lead to digestive problems, including diarrhea and stomach upset. If you want to give your cat some treats, then oat milk is the perfect choice. 

However, it is important to note that milk, including cat milk alternatives, should only be used as an occasional snack and not as a substitute for a balanced feline diet. Water is the most important and appropriate drink for cats to stay hydrated.

How Much Oat Milk Can Cats Have?

To ensure the well-being of your cat, it is generally recommended to offer only a small amount of oat milk in their bowl, possibly diluted with water. The quantity should be adjusted based on your cat's size. Additionally, it is advisable to limit the frequency of oat milk consumption. Ideally, you should treat your cat to oat milk only once a week or even less frequently. The occasional indulgence will be sufficient to spark their excitement.

It is crucial to avoid establishing a regular routine of providing your cat with excessive amounts of oat milk. Although oat milk may serve as a healthier alternative to dairy, particularly for breeds prone to lactose intolerance, it can still disrupt their digestive system and impact hormonal levels.

Therefore, remember to offer just a teaspoon or two of oat milk once a week, ensuring not to exceed this amount.

What Symptoms Show That Oat Milk Hurt Your Cats?

If a cat consumes oat milk or any other food that is not suitable for its digestive system, it may exhibit various symptoms indicating discomfort or potential harm.

Gastrointestinal Distress

Cats may experience digestive issues such as vomiting, diarrhea, or constipation after consuming oat milk. These symptoms may be accompanied by abdominal discomfort or bloating.

Lethargy or Weakness

Oat milk does not provide the necessary nutrients that cats need, and a cat's energy levels may be affected. If your cat appears unusually tired, weak, or lacks its usual activity levels, it could be a sign of nutritional deficiencies or an adverse reaction to the oat milk.

Allergic Reactions

Cats can develop allergies to certain foods, including plant-based ingredients like oats. Allergic reactions may manifest as skin irritations, itching, rashes, or even respiratory symptoms such as sneezing or difficulty breathing.

Changes in Behavior or Appetite

Cats may display changes in behavior, such as decreased appetite or reluctance to eat, after consuming oat milk. They may also exhibit signs of discomfort or restlessness.

Increased Thirst or Urination

If oat milk contains additives like sugar or artificial sweeteners, it may lead to increased thirst and urination in cats. Monitoring your cat's water intake and litter box habits can provide insights into any changes.

Cats should generally avoid consuming flavored or sweetened oat milk. These types of oat milk may contain additives, flavorings, or sweeteners such as sugar, artificial sweeteners, or other ingredients that can be harmful to cats. It is best to stick to plain, unsweetened oat milk without any additional flavors or additives when considering giving it to your cat.

Can Cats Drink Lactose Free Milk?

Lactose-free milk is, of course, milk in which the lactose has been removed or broken down into simpler sugars, making it easier to digest for people who suffer from lactose intolerance. While lactose-free milk may be better tolerated by certain cats compared to regular milk, it is crucial to be mindful of the additives present in the milk. Nowadays, many lactose-free milk products come with a range of additives, and it is important to avoid any inclusion of xylitol, as it is toxic to cats.


Oat milk may be a suitable option for humans seeking alternatives to dairy, it is not recommended as a regular part of a cat's diet. Cats require a diet rich in animal protein and specific nutrients that are not adequately provided by oat milk. Always prioritize your cat's health and consult with a veterinarian to ensure they receive a balanced and appropriate diet.
