Why do cats like milk if they are lactose intolerant?

It seems that cats love most high-fat dairy products such as milk and cream. However, why do they still eat these even if they don’t tolerate lactose well?

The reason for this might have something to do with the evolutionary history of cats. All animals have a hard time finding shelter and food when out in the wild. It is likely that food is scarce during winter even in abundant areas.

This is the reason why fat stores are found in mammals. Wild cats convert the unused energy that came from the excess food they ate during summer to fat and store this for use later on. This is the reason why animals love foods high in calories, proteins, and fat.

Sadly, cats don’t know that they no longer live in the wild or their bodies at least don’t know it. So, every time they see foods dense with high fat, they want to devour them.

If cats are lactose intolerant why can they eat cheese?
