Basically, milk is not good for cats

A funny story is that people always believe the milk is for cats, bones are for dogs and cheese are for mice. Undoubtedly, lapping up a tasty white drink can attract much attention of little cats. But, they are in trouble with digesting milk all the time.

Nutritious absorption from milk in cats is not thinkable. According to experts, milk is just an occasional commercial treat that contains a high calorie level for cats. Normally, the amount of calories a cat should be fed per day is 20 or 30 from unbalanced sources like commercial products. 83 and 149 are calorie levels in each cup of skim milk and whole milk respectively. These are too much for an ideal cat diet and leading to serious obesity easily.

By researches, a large number of cats are not tolerant of lactose. It is the most important reason why milk is bad for cats. In fact, many cat owners have really understood of lactose intolerance with their feline friends yet. Let’s learn more about the problem by answer two basic questions, what it is and how it has negative effects on the cat’s health.

What is it?

It is the lactase which is a type of enzyme which most cats have very little or even do not have in the body. Hence, the lactose in milk is impossible to digest. Then such sugar keeps staying in the intestinal system and brings a lot of bacteria. After fermenting, the sugar results in reactions in both the stomach and the gastrointestinal, cause cats to be painful.

Lactose intolerant occurs with 100% adult cats. For kittens, the probability declines when they still drink milk from mother but it will go on the opposite side when the kitty gets older. That kittens stop absorbing mother milk means the lactose enzymes do not keep producing. In fact, it is hard for you to know whether your cat is intolerant with lactose milk or not. So, being careful is still better.

How does it have negative effects on the cat’s health?

As mentioned above, the milk consumption of cats can influence the intestinal system negatively. One of the typical discomforts that cats suffer is distress in the digestive. It is totally not the same as the allergic when there is a bad response from the immune system to certain food consumption.

Some typical symptoms to know that cats are not lactose tolerant include diarrhea, dehydration, vomiting and so far. Moreover, cats can also face costiveness, painful stomach, and dry gums.
