Are cats lactose intolerant?

In this short article, we will answer the question “Are cats lactose intolerant?” and make a deep analysis of cats’ dairy consumption.

Images of cats consuming milk or pursuing it are frequently recalled. Additionally, certain commercials, movies, and images encourage this mindset by featuring kittens with milk-white fur and wet moustaches. 

But can cats actually consume milk the way we typically see them do?

It’s crucial to learn more about this behaviour, which may or may not be harmful to your cat’s health if you plan to adopt or already own cats. We must first comprehend how cats’ bodies function, particularly those of kittens, in order to find out.

Are cats lactose intolerant?

 Not typically. Some cats, like some people, may have lactose intolerance, though. But it’s crucial to understand whether milk endangers cats’ health in any way. 

Since cats are mammals and breastfeed when they are newborns, the answer to this issue is not so straightforward. It turns out that cats’ digestive systems undergo modifications as they develop, much as humans do. 

The production of the enzyme lactase, which breaks down lactose, has decreased, and this is one of the main ones. To put it another way, data indicates that a sizable percentage of cats develop lactose intolerance as adults.

What signs of lactose intolerance do cats exhibit?

Simply keep in mind if your kitten has ever had or typically experiences one of the following after ingesting milk to determine if he falls into the lactose-intolerant category:

  • diarrhoea,
  • discomfort in the abdomen, 
  • vomiting, 
  • cramps.

You’ll observe that these symptoms are strikingly similar to those of lactose intolerance in people. This is just another justification for not wanting to put your pet through this agony and for not thinking that cats can consume milk.

Allergies X Intolerance

There may be yet another reason for the cat to avoid dairy products, which helps put an end to the idea of the cat enjoying a bowl of milk: we’re talking about lactose allergy.

While intolerance affects the digestive tract, allergy is an immune system reaction. The signs can, however, be remarkably similar to those of intolerance. Therefore, as soon as you notice that your kitten has displayed any of the aforementioned symptoms, seek out a veterinarian.

Could kittens consume milk?

So if kittens can drink milk since cats initially consume it and only develop an intolerance to it over time, isn’t that good news? Not exactly. 

That’s because breast milk, which contains sufficient levels of lipids, proteins, and nutrients that the puppy requires, has a different composition from cow’s milk. A woman should speak with a veterinarian if a kitten’s mother is not present to provide milk.

He will be able to provide advice on the best food for a newborn cat and suggest a ready-made, particular blend to fulfil the demands of the kitten.

What happens if the cat isn’t allergic to anything or intolerant to lactose?

You cannot provide milk to cats, even if the animal is not allergic to it or intolerant to lactose. This is due to the fact that dry or wet rations are the greatest choice to provide a nutrient-dense and balanced diet for your cat. 

On the other side, milk has little nutritional value for him, therefore it is preferable to stay away from it. Bear in mind that cats should never consume cow’s milk. That’s because the chemical has qualities that could hurt a cat’s body. 

Other milk from herbivorous animals like goats and sheep falls under this category. It is therefore better to set ideas like creating cat milk aside if you’re thinking about how to make your cat happy.

In any case, should I give the kitten milk or not?

It is advised against insisting on including milk in your cat’s diet because the body can reject it. Cats can have lactose intolerance just like humans do. The symptoms include stomach ache, belly swelling, nausea, vomiting, diarrhoea, and gas. 

The assertion that all cats are lactose intolerant is untrue, yet it is still not advisable to take a chance.

Cats require food, wet or dry, that contains the nutrients they need to grow. Milk is not necessary for adult life, because cow’s milk contains more fat and sugar than the body can properly process.
