My cat just got a shot at the vet, and now she has diarrhea with what looks like colitis symptoms. Is this a common reaction or should I be worried?

My cat had a shot at the vet a day ago, and now she’s experiencing diarrhea and what appears to be colitis symptoms. She seems uncomfortable, and it’s making me anxious. Is this a typical reaction after vaccinations, or is it something I should be concerned about?

Answer

Your cat's recent vaccination may cause mild side effects like diarrhea or colitis, but it's crucial to monitor her for persistent or worsening symptoms.

  • Diarrhea and colitis can sometimes occur after vaccinations.
  • Watch for improvement or worsening over the next 24–48 hours.
  • If concerned, contact a veterinarian for personalized advice.

It is not uncommon for cats to experience mild gastrointestinal upset after a vaccination as their immune system responds to the vaccine. These symptoms should usually resolve on their own within a few days. However, if your cat appears very uncomfortable, seems to be getting worse, or has additional symptoms like vomiting or lethargy, it would be wise to reach out to a vet for guidance.

Book a consultation with a licensed vet at Dial A Vet for just $49 AUD if you're unsure or symptoms are getting worse.
