Can Cats Drink Evaporated Milk?

Evaporated milk is a shelf-stable processed, canned milk product with less water content than regular milk. Cats have trouble digesting even small amounts of lactose, so the original question was asked if cats could drink evaporated milk. Evaporated milk has much less lactose, which means cats can drink it without having too many digestive problems.

In most cases, cats should not consume evaporated milk. Cats have lactase enzyme deficiencies that can cause a hypersensitivity to the sugar found in milk. Evaporated milk is a dairy product with about 60% of the water removed from whole milk and contains about 40 grams of sugar per 240ml serving.

Can Cats Drink Evaporated Milk?

Cats cannot drink evaporated milk because it is not a liquid. It is just whole milk that has been boiled and dried. Evaporated milk is lactose intolerant. Cats have trouble digesting lactose, the sugar found in milk, which is why it is recommended that cats not be fed cow’s milk.

Evaporated milk is concentrated milk made by removing some water from regular dairy to concentrate its flavor and nutritional value. It has about 97% less water than regular milk, so evaporated milk doesn’t spoil as quickly as everyday dairy products like cheese or butter.

Evaporated milk contains about 85% water, 9% fat, and 6% protein, while the rest is lactose (milk sugar). Cats cannot digest lactose, so they cannot consume evaporated milk either.

If you make your cat food, you can make evaporated milk by adding 1 cup of water to every 1/2 cup of condensed or evaporated (milk). Then you can be whisking it together until it becomes smooth and creamy like regular cream humans.

Why Can’t Cats Drink Evaporated Milk?

Do you know why cats can’t drink evaporated milk? Cats lack the enzyme needed to digest the sugar in milk and cannot digest it. Evaporated milk contains about one-third of its water content, which gives the milk a higher concentration of sugar. The enzymes that cats produce in their body use a lot of the body’s resources to crack down lactose, a kind of sugar found in cow’s milk.

These are the key reasons why can’t cats drink evaporated milk:

Health Risks

Cats have a susceptible digestive system and can be severely impacted by drinking evaporated milk. Cats cannot properly digest lactose, the sugar in dairy products like evaporated milk. The resulting health problems are usually diarrhea or vomiting.

Lactose Intolerant

Cats cannot digest lactose, and cats also lack the enzyme necessary for proper digestion of protein. As a result, they suffer from kidney failure, malnutrition, and other health complications related to protein deficiency when consuming too much-evaporated milk.

Milk Allergy

Evaporated milk is milk that has been dried out and then powdered. It is often used in baked goods, soups, sauces, or other dishes.

Milk allergies are an immune system response to the proteins found in cow’s milk. In some cases, it can be caused by a reaction to the sugars in evaporated milk.

If your cat has a milk allergy, you should feed them with canned food instead of evaporated milk because they may react to it more than usual due to its high sugar content.

Cats Need Only Water For Hydration

Evaporated milk is not the same as milk that has been boiled. Evaporated milk can also be called condensed milk or dry milk. It is made by removing all the water from whole milk and then heating it to remove more moisture. It has a long shelf life because of its lack of water content, making it perfect for long-term storage.

The very first thing that reaches to mind is ensuring your cat has access to clean water. Cats need a lot of water, but they don’t always drink enough.

Here are some ways you can make sure your cat drinks enough water:

  • Get a pet fountain for cats and give them fresh, filtered water in the morning and night.
  • Fill a bowl with fresh, filtered water for your cat to drink from during the day when you’re not home or if you’re going away for a few days and want them to have access to pure drinking water while you’re gone.
  • Set up an automatic timer on your dishwasher so it runs every day before bedtime. So there’s plenty of fresh, filtered drinking water available for them each time they wake up in the morning.


In conclusion, cats can drink evaporated milk, but the effect on their kidneys is unknown. As always, consult your veterinarian before trying anything new.

Although it is not recommended for cats to drink evaporated milk due to negative side effects, they can drink it. Cats are more likely to be lactose intolerant than dogs, so they’re more likely to have adverse reactions if they drink the milk.
