Why does my cat’s vomit look like poop?

SEEK IMMEDIATE PROFESSIONAL TREATMENT IF YOUR CAT’S VOMIT LOOKS LIKE POOP.

Your cat is vomiting foul material that looks and smells like faeces. The probable causes are:

1. Blunt abdominal trauma – i.e. hit in the abdomen either through an accident or deliberate act.
2. Intestinal obstruction.
3. Peritonitis – wet form Feline Infectious Peritonitis (FIP). There’ll also be a high temperature, anaemia, dehydration and diarrhoea. Cats die within two months. It is an awful illness. It is caused by a coronavirus but not the one that has been in the news for the past several months.

There is nothing more for me to say because this is entirely a matter for a good veterinarian. Don’t use a veterinarian who declaws cats if at all possible. These are veterinarians who have a jaundiced attitude to feline welfare and who are prioritising profit over their patient’s health.
