The milk myth Cats and milk seem to be inextricably linked. But should a cat actually be allowed to drink regular milk?
Honestly, the answer is simply no. A cat doesn't need milk as a part of its nutrition. It can even cause diarrhoea.
Milk contains milk sugars such as lactose, and cats are unable to digest these. This requires an enzyme that older cats don't produce. If you do give milk to your cat, it can cause gastrointestinal problems.
Milk can cause diarrhoea.
Some cats do really like milk. Since cats naturally drink very little, a special cat milk, or for example giving a wet food, can be a great way to give them more fluid and thus keep the urinary tract healthy. Special cat milk is available that has no lactose. Attention: only give this milk as a treat!
