All cats drink their mother’s milk after they are born. It provides them with the proteins and fats necessary for growth and development, and they must drink that milk in order to survive. Orphaned kittens should not be given cow’s milk. They should get a specially designed kitten formula, which can be purchased from a vet.

The weaning process for a kitten begins at about four weeks of age, and by three months old, most kittens have developed lactose intolerance. Adult cats do not normally drink milk, especially those that are stray or feral. While domesticated cats may be given cow’s milk occasionally, it is not a necessary part of the feline diet. Most cats are lactose intolerant and cannot properly digest cow’s milk. Gastric problems and diarrhea usually follow a cat’s consumption of milk.

Milk can be given occasionally in small amounts if the cat can handle it. This can be a treat that you give your cat. If you try to make milk the only source of nutrition for your pet, he or she will die from malnutrition, as it does not contain the essential ingredients necessary to sustain a healthy feline.

If your cat absolutely loves milk, but cannot tolerate it, you can try to treat your special pet to lactose free brands. These products can be found in pet stores, and are specifically designed with feline digestive systems in mind. Such brand names as “Cat Sip,” and “Whiskas Soy Milk for Cats” are two products that many lactose intolerant cats can drink.

If your cat becomes very ill after ingesting milk and the sickness does not dissipate, consult your veterinarian for treatment.
