Are these vaccines supposed to make my cat feel lethargic or sick afterward? Just trying to figure out if this is a normal reaction or if I need to call the vet.

Yesterday afternoon, my cat received his routine vaccines, and since then, he seems a bit lethargic and not his usual playful self. Is it normal for cats to feel under the weather following vaccinations, or is this something I should be concerned about and contact the vet for?

Answer

It's normal for some cats to experience mild lethargy and discomfort after receiving vaccinations. This is usually a temporary reaction that should resolve within a day or two.

  • A slight decrease in energy is common after vaccinations.
  • Monitor your cat's symptoms for any changes.
  • If symptoms persist or worsen, consult your veterinarian.

After receiving vaccines, some cats may feel a bit under the weather as their immune system responds to the vaccine. This can cause temporary lethargy and a decrease in their usual activity levels, but they should bounce back to their normal selves shortly. If your cat shows signs of more severe reactions or if symptoms persist beyond 48 hours, it's best to consult with your vet.
