Can Cats Drink Milk? The Truth Behind This Common Myth
Can cats drink milk, or is it actually bad for them? Many people grow up believing milk is a natural treat for cats, but the reality is very different. While some cats may seem to enjoy it, milk is not always safe — and for many cats, it can cause digestive problems.
Why Do Cats Like Milk So Much?
Cats are attracted to the smell and fat content in milk. It tastes rich and appealing, which explains why many cats eagerly lap it up when given the chance. However, enjoying something doesn’t always mean it’s good for them.
Can Cats Digest Milk Properly?
Most adult cats are lactose intolerant. This means their bodies struggle to digest lactose, the natural sugar found in milk. When lactose isn’t broken down properly, it can lead to stomach upset.
Common reactions include:
- Diarrhea
- Gas and bloating
- Vomiting
- Abdominal discomfort
Even small amounts of milk can trigger symptoms in sensitive cats.
Is Milk Ever Safe for Cats?
In small amounts, milk isn’t toxic, but that doesn’t make it a good choice. Kittens can digest their mother’s milk, but as cats grow older, they lose the enzyme needed to process lactose efficiently.
If you want to offer milk, lactose-free cat milk is a safer option and is specially formulated for feline digestion.
According to experts in feline digestive health, water should always be the primary source of hydration for cats.
Better Alternatives to Milk
Instead of regular milk, consider:
- Fresh, clean water (always available)
- Cat-safe lactose-free milk (occasional treat)
- Wet cat food for added hydration

When Milk Becomes a Real Problem
If your cat experiences repeated stomach issues after drinking milk, it’s best to remove it entirely from their diet. Cats with sensitive stomachs or digestive conditions should avoid milk altogether.
If diarrhea continues, switching to gentler food options can help. You may find useful guidance in our article on the best food for cats with diarrhea.
So, can cats drink milk? Technically yes — but for most cats, it’s not a good idea. While milk isn’t poisonous, it often causes digestive discomfort and offers little nutritional value.
Fresh water and a balanced cat diet remain the safest and healthiest choices.
