Every time a cat catches a whiff of milk, there's no mistaking the excitement in their eyes. Whether it's the creamy texture or the rich taste, milk seems to be one of those foods that cats just can't resist. It's a classic image—cats sipping from a bowl of milk, often seen in cartoons and movies. But, as tempting as it may be to offer your furry friend a taste, you might wonder: Can cats really drink milk? Is it safe? Will it make them sick?
Here, I’ll uncover the truth about milk for cats, the potential dangers of lactose intolerance, and what you can offer your cat as a safe and healthy alternative.
Why Cats Can’t Drink Cow Milk: Lactose Intolerance
Many cat owners are under the impression that milk is a tasty treat that can be given as a snack. After all, cats are often depicted in media sipping milk from a saucer. However, milk can actually cause digestive issues for many cats. This is mainly because most adult cats are lactose intolerant.
Lactose is a type of sugar found in milk, and cats don’t have enough of the enzyme called lactase that is needed to break down lactose. As a result, when a cat drinks milk, the lactose remains undigested in their intestines, leading to uncomfortable symptoms like:
- Diarrhea
- Vomiting
- Stomach cramps
Studies show that up to 65% of adult cats are lactose intolerant, and the likelihood of lactose intolerance only increases with age. Kittens are born with the ability to digest their mother's milk, but after weaning, they gradually lose the ability to digest lactose, making milk less tolerable as they get older.

Signs of Lactose Intolerance in Cats
It’s not always obvious when a cat experiences lactose intolerance, but there are some common signs to watch out for:
- Diarrhea: This is usually the first noticeable symptom. If a cat is given milk and then experiences diarrhea within hours, lactose intolerance could be the cause.
- Vomiting: Some cats may vomit after drinking milk, especially if they’re not used to it or are lactose intolerant.
- Stomach bloating: An unhappy stomach can lead to bloating, discomfort, and restlessness in a cat.
- Change in behavior: Cats that experience discomfort might become irritable or seek out a quiet, isolated place to rest.
If any of these symptoms occur after giving milk, it’s best to avoid offering it in the future and opt for safer alternatives.

What About Kittens? Can They Drink Milk?
Kittens, especially newborns, need milk for proper growth. However, this is not cow’s milk but specifically formulated kitten milk replacers. Cow's milk does not provide the right nutrients that kittens need, and it can cause digestive upset.
In the first few weeks of life, kittens should nurse from their mother. If the mother is unavailable, a kitten milk replacer is recommended. These are specially formulated to match the nutritional profile of mother’s milk.
For kittens over eight weeks old, transitioning to solid food and fresh water is ideal. Milk, even in small amounts, is no longer necessary, and at this stage, lactose intolerance can become more prominent.
What Are the Alternatives to Cow Milk for Cats?
If milk isn't safe for most cats, what can be given as an occasional treat? Thankfully, there are plenty of milk alternatives and healthy options to keep a cat happy without causing digestive issues.
- Lactose-free milk: Some pet stores sell specially formulated lactose-free milk designed for cats. This type of milk contains the same creamy texture and flavor as regular milk but without the lactose. If a cat enjoys milk and you want to give it a treat, lactose-free milk is the best option.
- Cat milk replacer: For kittens or adult cats in need of extra nutrition, there are commercial cat milk replacers available. These are designed to provide essential nutrients and are free from lactose, making them much safer for cats.
- Water: Fresh water should always be the primary beverage for a cat. Staying hydrated is crucial for maintaining a healthy weight, good digestion, and overall well-being. Water helps with kidney function, digestion, and helps cats flush toxins out of their system.
- Broths and soups: If a cat is reluctant to drink water, low-sodium broths (without onions or garlic) can be a good alternative. These are both hydrating and delicious, offering a nice treat without upsetting their stomachs.
How to Treat Lactose Intolerance in Cats
If a cat has already consumed cow's milk and is showing signs of discomfort, here’s what can be done:
- Hydration: Keep the cat hydrated by offering fresh water or a pet-safe broth. Hydration helps flush out any lactose from their system and prevents dehydration caused by diarrhea or vomiting.
- Monitor symptoms: If the symptoms are mild, like slight bloating or diarrhea, they may resolve on their own after a few hours. But if symptoms persist, it’s important to consult with a veterinarian.
- Avoid milk: The best way to treat lactose intolerance is to stop giving milk altogether. Milk isn't a necessary part of a cat’s diet, and it should not be used as a regular treat.
What to Do if a Cat Drinks Milk Accidentally
Sometimes, despite best efforts, a curious cat might get into a glass of milk. If this happens, it’s important to keep a watchful eye on the cat for the next few hours. If signs of digestive upset appear, keep the cat comfortable, hydrated, and monitor their behavior. If symptoms worsen or if the cat seems to be in pain, consulting a veterinarian is always the safest option.
Can Cats Ever Drink Cow Milk?
While some cats may seem to tolerate small amounts of cow's milk without showing signs of distress, this is more the exception than the rule. Even if a cat doesn’t immediately react poorly, it doesn’t mean that milk is safe for regular consumption. Cats are obligate carnivores, meaning their bodies don’t require dairy, and many cats simply can't digest it properly.
In the end, there are many delicious, safe alternatives for treating a cat without the risk of digestive issues. From lactose-free milk to fresh water and tasty broths, there are plenty of ways to keep a cat hydrated and happy without relying on milk.
Final Thoughts
While the classic image of a cat enjoying a bowl of milk is charming, the reality is that milk isn't the best treat for most cats. Lactose intolerance is common, and drinking cow's milk can lead to uncomfortable digestive problems. But there’s no need to worry—there are many other delicious and safe alternatives to offer instead.
Cats might not get to sip on a saucer of milk, but they can still enjoy a variety of other treats that keep them healthy and satisfied. Understanding what works best for a cat’s digestive system ensures a happier, healthier pet.
