Every cat owner has likely witnessed their feline friend’s fascination with milk. Whether it’s batting at your cereal bowl or eagerly lapping up spilled milk, cats often seem drawn to this creamy beverage. This can lead to the common question: Is it safe for cats to drink milk? And if not, why do cats seem to love it so much? Let’s delve into the truth about cats and milk, exploring whether it’s a healthy treat or a dietary no-no for your feline companion.
The Unsurprising Answer: Milk Isn’t Ideal for Cats
Despite their apparent love for it, cow’s milk is generally not good for cats, particularly adult cats. There are several key reasons behind this, with the primary culprit being lactose intolerance. Just like many humans, a significant number of cats develop lactose intolerance as they mature. This condition stems from a decrease in lactase, the enzyme responsible for breaking down lactose, the sugar found in milk.
When lactose-intolerant cats consume milk, their digestive systems struggle to process it. This undigested lactose leads to a host of gastrointestinal issues, including:
- Diarrhea
- Vomiting
- Gas
- Abdominal discomfort

While not all cats are strictly lactose intolerant, the problems with cow’s milk don’t end there. Cow’s milk is also relatively high in fat. Many cats, especially indoor cats, are already predisposed to obesity. Regularly offering milk to your cat can contribute to an unbalanced diet, adding unnecessary fats and sugars that can lead to weight gain and related health problems over time.
However, like many dietary considerations, moderation is key. If your cat isn’t lactose intolerant and shows a strong fondness for milk, a very small amount, like a teaspoon or two once or twice a week, is unlikely to cause significant harm. But, larger portions or more frequent servings can certainly pave the way for digestive issues and long-term health concerns.
Spotting Lactose Intolerance in Your Cat
Wondering if your cat is among those with lactose intolerance? Observing your cat after they’ve consumed milk can offer clues. Lactose intolerance symptoms typically appear within 12 hours of consuming dairy products. Keep an eye out for:
- Vomiting
- Diarrhea
- Excessive gas
- Signs of stomach upset or discomfort
If your cat exhibits these symptoms after drinking milk, lactose intolerance is the likely cause. In most cases, lactose intolerance in cats is self-limiting. This means the symptoms will usually resolve on their own without specific treatment, often within 24 hours. However, it’s crucial to monitor your cat for dehydration, especially if diarrhea or vomiting is severe.
If your kitty is showing signs of vomiting, diarrhea, and gas within about 12 hours of eating a milk product, they are most likely lactose intolerant.

While mild lactose intolerance usually resolves within a day, it’s essential to seek veterinary care if your cat experiences prolonged illness (lasting over 24 hours), persistent vomiting that prevents them from keeping down water, or exhibits signs of lethargy. These symptoms could indicate dehydration or a more serious underlying issue.
Navigating Milk Alternatives for Cats: Proceed with Caution
Given the issues with cow’s milk, you might consider plant-based or nut-based milk alternatives like oat milk, soy milk, almond milk, or coconut milk as a seemingly safer option for your cat. Unfortunately, these alternatives are also generally not recommended for feline consumption.
Many of these milk alternatives can present their own set of problems:
- High Fat Content: Similar to cow’s milk, some plant-based milks can be high in fat, contributing to weight gain.
- Digestive Issues: These alternatives often contain sugars, oils, and thickeners that can be difficult for cats to digest, leading to gastrointestinal upset.
- Additives and Preservatives: The additives and preservatives present in many commercial milk alternatives can also be problematic for feline digestion.
- Added Salt: Some plant-based milks contain added salt. While a small amount of salt isn’t inherently harmful, it’s not ideal for cats prone to hypertension or kidney disease.
Milk for Kittens: A Different Story (But Still Species-Specific)
Kittens, unlike adult cats, are born with the ability to digest lactose. They produce lactase, enabling them to process their mother’s milk effectively. This is why young kittens can happily consume cat milk without digestive distress. However, this ability diminishes as they wean and transition to solid food, typically around 8 weeks of age.
It’s crucial to remember that even for kittens, the appropriate milk is cat milk, specifically milk produced by female cats. Cow’s milk, or milk from other species like sheep or goats, is still not suitable for kittens. If you have orphaned kittens or kittens needing supplemental feeding, specialized kitten milk replacers are available. Products like PetAg KMR liquid and powder milk supplements are formulated to mimic the composition of cat milk and provide the necessary nutrients for healthy kitten development. Even dog milk replacers are not appropriate for kittens due to their unique nutritional requirements.
Kittens are only able to drink milk produced by female cats—not milk from any other species such as cows, sheep, or goats.

The Best Hydration for Cats: Sticking to Water
When it comes to beverages for cats, simplicity is best. Water is, without a doubt, the most healthy and essential drink for cats of all ages. Cats are naturally prone to dehydration, so ensuring they have access to fresh, clean water is paramount for their overall health and well-being.
To encourage your cat to drink more water, you can try various appealing methods:
- Multiple Water Sources: Offer water in different locations around your home.
- Water Fountains: Many cats are attracted to moving water and may drink more from a pet water fountain.
- Flavorful Water: Add a small amount of tuna juice (from canned tuna in water, not oil) to their water bowl to entice them to drink.
- Wet Food Hydration: Supplement their water intake by adding a few tablespoons of water to their canned food to create a hydrating “soup.”
By making water readily available and appealing, you can provide your cat with the best possible hydration, far surpassing any potential (and limited) benefits they might derive from milk. Water truly is the healthiest and most beneficial drink for your feline companion.
