My cat has diarrhoea, what should I do?

Veterinary treatment for diarrhoea in cats is not always necessary as it will often resolve on its own. If caring for a cat with diarrhoea at home don’t withhold food, make sure your cat has plenty of fresh water available and encourage them to drink to avoid dehydration.

Monitor your cat carefully and contact your vet or, out of hours, your nearest Vets Now if:

  • Your cat’s diarrhoea doesn’t resolve within 24 hours
  • Your cat is very old, young or suffers from an underlying health condition
  • They show signs of lethargy, depression or pain
  • They are vomiting
  • The diarrhoea is watery, explosive or persistent
  • There is blood in the diarrhoea or it is very dark
