Why can kittens drink milk?

A lot of us have seen an image of cute kittens drinking milk before. But have you wondered why felines can drink milk at a young age and not during their adult years?

That’s because adult felines have a difficult time digesting milk. Unlike adult cats, kittens have the needed enzymes in their stomachs to break down the lactose in the milk. So, if an adult cat drinks milk, they’re more likely to have a stomachache.

Kittens can digest milk and lactose until they’ve been weaned. That means they can drink milk until they’re about eight weeks old. After that, dairy may not be the best option for your kitten.

There’s no need to feed your kitten any type of milk apart from their mother’s milk. It already contains all the nutrients that the kitten needs for growth and development.

However, if your cat is an orphan, you should opt to get kitten formula milk or lactose-free milk. That can reduce the chances of getting a stomachache. 

Why shouldn’t you feed your cat milk?

We’ve all heard that there’s nothing more than a cat loves than a fresh bowl of milk. But we’re sorry to inform you, but that isn’t true.

In fact, cows milk isn’t a natural part of a cat’s diet and can be considered harmful to some. Although your cat may like milk because of the creamy content, it doesn’t always mean that it’s good for your cat to drink it.

Cats are very sensitive animals. So, even a small amount of milk could make your cat feel uncomfortable and lead to sicknesses such as mild manifestations, diarrhea, vomiting, etc.

Depending on your type of cat, there are many reasons why cats can’t drink milk. One of the main reasons is because most cats can be lactose intolerant. Similar to most mature mammals, some cats can be lactose intolerant. That means that their body isn’t able to break down lactose, which is the sugars in milk.

So if the type of milk you’re feeding them contains a large amount of lactose, they might not have the needed enzymes to absorb and break down the lactose, which will result in an upset internal digestive system.


If you’ve accidentally fed your cat some milk, don’t worry. Although it shouldn’t have a significant effect on your cat, here are a few symptoms to keep a close eye on when taking care of your cat.
