What is diarrhoea in cats?
Diarrhoea is faeces that are soft to liquid in consistency. If your cat has diarrhoea they may strain to pass faeces and you may see blood, mucous, parasites, or foreign objects in the faeces.

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

The seriousness of a cat's diarrhoea is determined by the characteristics of the diarrhoea itself and any associated signs, as well as your cat's general health.
What are the causes of diarrhoea in cats?
Diarrhoea is a common problem with a wide variety of causes. Cats are less likely to get diarrhoea than dogs since they tend to be a bit more careful about what they eat.
Common causes of diarrhoea in cats include parasites, infection and colitis. Cats may have diarrhoea as a result of eating inappropriate products, such as non-food items or due to intolerance to certain foods, such as lactose.
How will my vet treat my cat with diarrhoea?
Initial treatment for cat diarrhoea is focused on controlling the signs. Your cat may be given medication for parasites, antidiarrhoeal medication, and in some cases antibiotics. In severe cases your cat may need fluids for dehydration (under the skin or a drip are most commonly used).
How can I prevent my cat from getting diarrhoea?
Keeping your cat on a consistent diet and minimizing his or her exposure to things likely to cause diarrhoea is the best form of prevention.
My cat has diarrhoea, should I stop them eating?
Don't withhold food from your cat if they have diarrhoea as this can prevent the intestinal tract from healing. This can result in hepatic lipidosis, also known as fatty liver, which is a very serious, and potentially life-threatening liver disease.
