My year-old cat suddenly won't eat after getting his vaccines—should I be worried or is this normal, Dial A Vet?

I took my year-old cat to the vet yesterday for his vaccinations, and today he seems completely uninterested in his food, which is unusual for him. Is it common for cats to lose their appetite after getting vaccinated, or do I need to be concerned about something else going on?

Answer

It is not uncommon for cats to experience a temporary loss of appetite following vaccinations due to the mild discomfort or mild fever they might experience. However, if your cat's lack of interest in food persists, it's important to monitor for other symptoms.

  • Temporary appetite loss can occur post-vaccination.
  • Monitor your cat for any additional symptoms.
  • Consult a vet if appetite loss persists or other issues arise.

Cats can experience mild side effects after vaccinations, such as a low-grade fever or feeling a bit under the weather, which might lead them to eat less or not at all immediately after the visit. This is typically temporary and they should return to their normal selves within a day or two. If your cat is still not eating after 24-48 hours or if you notice other symptoms such as vomiting or lethargy, it would be wise to follow up with your vet.
