Why do cats get diarrhea from milk? - briefly
Cats often experience diarrhea from consuming milk due to lactose intolerance. Most cats lack the enzyme lactase, which is necessary for breaking down lactose, the sugar found in milk, leading to digestive upset.
Why do cats get diarrhea from milk? - in detail
Cats are often depicted enjoying a bowl of milk in popular culture, but in reality, many cats experience digestive issues, including diarrhea, when they consume dairy products. This phenomenon can be attributed to several biological factors unique to felines.
Cats are obligate carnivores, which means their diet primarily consists of meat. Over millions of years of evolution, cats have adapted to derive most of their nutritional needs from animal-based proteins. As a result, their digestive systems are not well-equipped to handle large amounts of dairy. Milk, in particular, contains lactose, a sugar that requires the enzyme lactase to be broken down and absorbed in the digestive tract. Kittens produce lactase to digest their mother's milk, but as they grow older, the production of this enzyme significantly decreases or stops altogether. This condition is known as lactose intolerance.
When lactose-intolerant cats consume milk, the lactose passes undigested into the large intestine. Here, it ferments due to the action of gut bacteria, producing gas and drawing water into the intestine. This process can lead to symptoms such as bloating, abdominal discomfort, and diarrhea. The severity of these symptoms can vary among individual cats, depending on the level of lactose intolerance and the amount of milk consumed.
Moreover, some cats may also have allergies or sensitivities to the proteins found in cow's milk, such as casein and whey. These proteins can trigger an immune response, leading to inflammation in the digestive tract and subsequent diarrhea. Allergic reactions can also manifest as skin irritations, itching, and respiratory issues, but gastrointestinal symptoms are common.
It is crucial for cat owners to be aware of these potential issues and avoid giving their pets milk as a regular treat. There are specialized cat milks available in the market that are lactose-free and formulated to be safe for feline consumption. These products are designed to mimic the nutritional profile of a mother cat's milk and can be a healthier alternative for cats that enjoy dairy.
In summary, cats often get diarrhea from milk due to lactose intolerance and potential allergies to dairy proteins. Understanding these factors can help cat owners make informed decisions about their pets' diets and ensure their overall health and well-being.
