My kitten got her vaccine earlier today, but now she’s a bit lethargic and not interested in food. Is this normal, or should I call Dial A Vet?

I took my kitten to get her vaccine earlier today, but since then she's been acting a bit lethargic and hasn't shown much interest in her food. I'm concerned because she's usually quite playful and energetic. Is this a normal reaction to the vaccine, or is it something I should worry about and call for advice?

Answer

It's common for kittens to experience some lethargy and reduced appetite after receiving vaccinations. This reaction is generally mild and temporary.

  • Mild lethargy and decreased appetite can occur after vaccinations.
  • These effects are usually short-lived and should pass within 24 to 48 hours.
  • If symptoms persist or worsen, consulting a vet is advisable.

Vaccines help protect your kitten from serious diseases but can sometimes cause mild side effects, like tiredness or a decreased interest in food. These are typical responses as your kitten's body builds immunity. Usually, these symptoms will improve without intervention. However, if you're concerned or if your kitten’s condition doesn't improve, seeking professional advice is a good idea.

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

Frequently Asked Questions

  • How long should I expect my kitten to be lethargic after a vaccine?

    Most kittens will return to their usual playful selves within 24 to 48 hours following vaccinations. If lethargy persists beyond this period, it would be wise to consult a vet.

  • What should I do if my kitten doesn’t eat for a whole day after vaccination?

    While a short-term reduction in appetite is common, if your kitten refuses to eat for more than a day, contacting a veterinarian is recommended to ensure there are no other underlying issues.

  • Are there any signs to watch for that would indicate a more serious vaccine reaction?

    Serious reactions are rare, but watch for signs like swelling around the face, persistent vomiting, hives, or difficulty breathing. If you notice these symptoms, seek veterinary care immediately.
