A lot of people picture cats lapping up a bowl of milk and think itâs a perfect treat.
Honestly, thatâs not really the case. Most adult cats canât handle lactose, and milk usually gives them an upset stomach, diarrhea, or other digestive trouble.
Kittens drink their momâs milk when theyâre little, but as they get older, their bodies stop making the enzyme that digests lactose.
So milk just isnât a healthy or natural part of an adult catâs diet.
Some cats might still go for the taste, but itâs safer to stick with fresh water or special cat treats.
Knowing why milk isnât the best for cats helps owners avoid falling for a common myth and keeps their pets happy.
Can Cats Drink Milk?
People often ask if cats can safely drink milk or if itâs healthy for them.
While milk seems like a treat, most adult cats canât digest it well and end up with digestive problems.
Itâs worth knowing why cats like milk and the risks before pouring them a bowl.
Why Cats Are Attracted To Milk
Cats seem to like milk because itâs rich in fat and protein.
The creamy texture and taste hit their natural craving for fatty foods.
Kittens drink their momâs milk, which is packed with nutrients, so the flavor and smell are familiar to them.
But cowâs milk isnât the same as a catâs motherâs milk.
The sugars and proteins are different.
Cats might be curious or like the taste, but that doesnât mean milk is a good daily drink for them.
Lactose Intolerance In Adult Cats
Most adult cats canât digest lactose because they stop making the enzyme for it.
When they drink milk, the lactose just sits in their gut and ferments, causing stomach upset.
You might notice signs like:
- Diarrhea
- Gas
- Stomach cramps
- Vomiting
Feeding cowâs milk to adult cats usually brings more trouble than any benefit.
Kittens can handle milk when theyâre nursing, but that changes as they grow up.
Potential Health Risks Of Giving Cats Milk
Regularly giving cats milk can lead to ongoing stomach problems. Digestive upset is the most common issueâthink diarrhea and discomfort.
If the diarrhea gets bad, cats can become dehydrated.
Milk also adds extra calories and fat, which can lead to weight gain.
Some cats even get skin problems or allergies from drinking milk too often.
If you really want to offer milk, there are special lactose-free versions made for cats.
These donât cause the same digestive issues as regular milk.

Alternative Drinks And Safe Milk Options For Cats
Cats need drinks that are actually good for them.
Some specially made milks for cats have protein and calcium but wonât upset their stomachs.
Fresh water is always the best choice.
But there are a couple of other options if you want to mix things up.
Lactose-Free And Specially Formulated Cat Milk
Lactose-free milk made for cats is a safer pick than regular cowâs milk.
Itâs got the nutrients like protein and calcium, but without the lactose.
That means it wonât cause stomach problems or diarrhea like regular milk does for most cats.
Special cat milk formulas try to copy the nutrients kittens get from their momâs milk.
Theyâre high-calorie to help with growth and energy.
Manufacturers skip the nasty preservatives and artificial flavors, so these are safe for both kittens and adults.
If youâre using kitten milk replacement or special cat milk, stick to the package instructions for how much and how often.
That way, your cat gets the nutrition without tummy trouble.
Water And Other Healthy Alternatives
Fresh water should always be available for cats.
Some cats like running water, so a fountain can help them drink more.
Good hydration keeps their kidneys healthy and supports their general well-being.
Wet cat food can also help with hydration, since it contains moisture.
But donât count on milk or other drinks to keep your cat hydrated.
Cats shouldnât drink cowâs milk regularly because it can upset their stomach.
Stick to water or special cat milk for the safest bet.
Dangers Of Dairy And Plant-Based Milk For Cats
Since most cats are lactose intolerant, cowâs milk can cause stomach pain, gas, or diarrhea.
Dairy foods like cream or cheese should only be tiny treatsâif at all.
Plant-based milks like almond or soy arenât safe for cats either.
They often have preservatives, artificial flavors, or sugars that cats canât handle.
These ingredients can upset a catâs stomach or cause allergies.
Giving cats the wrong drinks too often can mess with their health and eating habits.
Sometimes, pet insurance might help with vet bills if cats get sick from unsafe drinks.
Itâs always best to stick with water or products made for cats.
