Is it normal for a pet to not eat two days after getting immunized?

My cat got her vaccinations two days ago, and ever since, she's barely touched her food. She usually has a good appetite, so it's unusual for her to skip meals like this. Could the immunizations be causing her to avoid eating, and is this something I should be concerned about?

Answer

Your cat's reduced appetite following her vaccinations can be concerning, but it's often a temporary reaction some cats experience. Monitoring her for a day or two may be all that's needed.

  • Decreased appetite can occur after vaccinations.
  • This usually resolves within 24 to 48 hours.
  • Consult a vet if your cat's appetite doesn't improve or other symptoms arise.

It's not uncommon for cats to experience mild side effects following vaccinations, including a temporary decrease in appetite. While this is generally not cause for alarm, it's important to keep an eye on her. Most cats feel back to normal within a couple of days. However, if she continues to avoid food or seems unwell, it might be best to consult a vet.
