Movies, cartoons, and storybooks have made a saucer of milk seem like the ultimate treat for a cat. In reality, many adult cats have difficulty digesting lactose.
Kittens produce the enzyme lactase to help them digest their mother's milk. As they grow and are weaned, lactase activity naturally decreases. That means dairy products can become much harder for an adult cat's digestive system to handle.
For a lactose-intolerant cat, drinking cow's milk may lead to digestive discomfort, including diarrhea, gas, or an upset stomach.
Your cat might eagerly drink milk if it's offered, but enjoying the taste doesn't necessarily mean their body handles it well.
For everyday hydration, fresh water remains the safest choice. If you'd like to offer your cat a special treat, choose something specifically formulated for feline nutritional needs.
