Why does my male cat keep vomiting after his booster shot, should I be worried?

My male cat received his booster shot yesterday, and since then he's been vomiting intermittently. He seems otherwise okay, but the vomiting has me concerned. Is this a normal reaction to the vaccine that will pass, or should I take him to see a vet?

Answer

It's understandable to be concerned when your cat starts vomiting after receiving a booster shot. While mild reactions are possible, it's important to monitor your pet's condition closely.

  • Monitor the frequency and severity of vomiting
  • Ensure your cat stays hydrated
  • Consult a vet if symptoms persist or worsen

Some cats may experience mild reactions after vaccinations, such as vomiting, lethargy, or slight swelling at the injection site. These symptoms typically resolve on their own within a day or two. However, if your cat's vomiting continues, becomes severe, or if your pet shows other concerning symptoms, it would be best to consult with a veterinarian. They can assess whether additional care is needed.

If this is an emergency, please seek immediate veterinary care.
