is milk ok for cats
Why Milk Is Bad For Cats Milk Is Bad for Most Cats. Most cats are lactose intolerant, like many humans. This means that they donât have the enzymes needed to digest the lactose in milk. Lactose is a type of sugar found in milk. When cats drink cowâs milk, they can end up with painful stomach cramps and diarrhea. This is because undigested lactose will stay in their intestines, rather than passing into the bloodstream, and end up fermenting because of bacteria.
