What is colitis in cats?

Colitis in cats is a digestive disease that causes inflammation of the colon – also called the large or lower intestine

It can cause pain and discomfort in your cat, as well as diarrhoea or constipation.

Brief summary...

What is colitis?

A relatively common condition, colitis can affect both animals and humans. Like many conditions, it’s usually described as chronic – meaning slow to develop, but persistent – or acute, meaning it flares up quickly and may be intense.

Colitis can be painful and uncomfortable for your cat, and is responsible up to half of all cases of chronic diarrhoea. While it’s relatively common and easy to treat, feline colitis can lead to inflammatory bowel disease (IBD), which is a more serious condition.  

If your cat is displaying any of the signs and symptoms of colitis listed below, make an appointment with your local vet.

Common causes of colitis in cats

Treating your cat's colitis

Your vet will recommend a treatment programme, depending on the severity of your cat’s condition. They'll usually recommend fasting for 24 to 48 hours, then introducing a special high-fibre or bland diet.

They may recommend a course of antibiotics or anti-inflammatory medication to treat any underlying infection, and a worming treatment to remove any gastrointestinal worms that can cause or exacerbate colitis.

While colitis can be painful and uncomfortable, it’s normally very treatable, and the prognosis is generally good. 

Can I prevent my cat from getting colitis? 

While it’s not possible to completely prevent feline colitis, taking the following steps may help to reduce your cat’s chances of developing it:

  • Get into a regular worming routine
  • Get into a regular flea treatment routine – as fleas can lead to worms
  • Keep your cat’s vaccinations up to date
  • Feed your cat a balanced, high-fibre diet and plenty of water to drink
  • Ensure your cat doesn’t eat things they’re not supposed to
  • Avoid sudden changes to your cat’s diet
  • Keep stress to a minimum
