My cat got vaccinated a couple of days ago, but now it's really lethargic and isn't eating much. Should I be worried?

A couple of days ago, I took my cat to get vaccinated. Since then, I've noticed she's become quite lethargic and hasn't been eating as much as she normally does. Is this normal post-vaccination behavior, or should I be worried and consider taking her back to the vet?

Answer

It's not uncommon for cats to experience mild lethargy and reduced appetite after vaccinations. These symptoms usually resolve within a couple of days.

  • Post-vaccination lethargy and decreased appetite are common.
  • Symptoms should improve within a day or two.
  • If symptoms persist or worsen, consult a vet.

Vaccinations are essential in protecting your cat from potentially serious diseases, and some cats may experience mild side effects. Feeling a bit tired and having a decreased appetite can be normal responses to the vaccine as their immune system is activated. Typically, these side effects are temporary and should resolve within a couple of days. However, if your cat's symptoms persist or you notice other concerning signs, it's best to seek veterinary advice.
