Why is my kitten acting weird after the live vaccine? I’m worried, is this normal?

After taking my kitten to the vet for a live vaccine yesterday, I've noticed she's been acting strange. She's more sluggish than usual, doesn't seem as interested in playing, and has been hiding more often. I'm worried this might be a reaction to the vaccine. Is this normal behavior after vaccination, or should I be concerned about something more serious?

Answer

It's common for kittens to exhibit some mild side effects after receiving a vaccine, including lethargy and reduced playfulness.

  • Mild sluggishness is normal after vaccination.
  • Observe for any concerning symptoms.
  • Contact a vet if symptoms persist or worsen.

After vaccinations, it's normal for kittens to experience some mild side effects, such as being a little more tired than usual or showing a decrease in playfulness. These symptoms typically subside within 24 to 48 hours. Hiding can also be a way for your kitten to find comfort if she's feeling a bit under the weather. However, if your kitten's behavior doesn't improve, or you notice severe symptoms like vomiting, facial swelling, or breathing difficulties, it's important to contact your vet.
