The Truth Behind Cats and Milk
•Posted on August 15 2018
Many people are under the impression that cats need to drink milk instead of water, however, that is not exactly true. Cats are in fact lactose intolerant which means that they don’t have the enzymes needed to digest the lactose in milk. The only time that cats should drink milk is when they are weaning, and this is milk from their mother or specifically formulated kitten milk. Kittens are born to digest the sugar in milk as this sugar is a valuable source of energy for young animals, but at around eight weeks of age the enzyme, lactase, that enables them to digest it disappears from the gut. After a kitten has been weaned, milk is not necessary in a cat’s diet. Milk, especially ordinary cow’s milk, can be very harmful to their health - causing severe sickness and diarrhoea. This is because the undigested lactose stays in their intestines rather than passing into the bloodstream, where it could possibly ferment due to the bacteria found there. The problems often appear around eight to twelve hours after drinking the milk, with the sickness and diarrhoea proving potentially fatal to young kittens as their body dehydrates very quickly. Milk can also be very high in fat. One saucer of milk is the equivalent to four burgers – based on an average sized woman and a 4.5kg cat. Fresh, clean water is the only drink cats need.
