Just got my cat vaccinated an hour ago and now she seems super sleepy. Is that a normal reaction?

I took my cat to the vet just an hour ago for her vaccinations, and now she's curled up and seems much sleepier than usual. I'm wondering if it's normal for her to be this tired after getting her shots, or if there might be something else going on. Should I be concerned about her being so lethargic, or is this a typical reaction to the vaccine?

Answer

It is quite common for cats to feel sleepy or lethargic after receiving vaccinations. This reaction is typically temporary and should resolve within a day or two.

  • Post-vaccine lethargy is normal in cats.
  • Symptoms usually resolve within 24 to 48 hours.
  • Provide a comfortable space for your cat to rest.

After vaccination, your cat's immune system is working to build defenses, which can make her feel more tired than usual. Lethargy, mild fever, and reduced appetite are common and should not last long. Ensure she has a quiet place to relax and keep an eye on her for any changes.

Book a consultation with a licensed vet at Dial A Vet for just $49 AUD if you're unsure or symptoms are getting worse.
