My cat just got vaccinated and now seems a bit lethargic and isn't eating much. Is this normal?

Yesterday, my cat went in for her routine vaccinations, but ever since we've been home, she's been unusually lethargic and hasn’t shown much interest in her food. I’m a bit concerned because she’s normally so active and has a healthy appetite. Is this a common reaction after vaccines, or should I be more worried?

Answer

It's not uncommon for cats to experience mild side effects such as lethargy and decreased appetite after vaccinations. However, if these symptoms persist or worsen, it's important to consult a vet.

  • Monitor your cat for any worsening symptoms
  • Ensure she is comfortable and has access to water
  • Contact a vet if lethargy or appetite issues don't improve in 24-48 hours

After receiving vaccinations, some cats may feel a little under the weather as their immune system responds to the vaccine. This can result in temporary lethargy or a reduction in appetite. Usually, these mild symptoms resolve within a day or two. Keeping her warm and ensuring she stays hydrated can aid in a quicker recovery. If these symptoms persist beyond 48 hours or you notice any other concerning changes, it would be prudent to seek veterinary advice.
