My cat isn't eating after getting vaccinated yesterday, should I be worried?

Yesterday, I took my cat to the vet to get her vaccinations, and since then, she hasn't shown much interest in eating. Normally, she loves her meals, so this change is quite noticeable. Is it normal for cats to lose their appetite after vaccinations, or should I be concerned about something more serious?

Answer

It’s common for cats to experience a temporary decrease in appetite after receiving vaccinations. This usually resolves within a day or two, but it’s important to monitor her closely.

  • Temporary loss of appetite is usually not a cause for concern.
  • Monitor your cat's behavior and eating habits for the next 24-48 hours.
  • Contact a vet if her appetite doesn't improve or if other symptoms arise.

Vaccinations can cause mild, short-term side effects in cats, including a lack of interest in food. This is a normal part of the immune response as her body adjusts. Most cats will return to their usual eating behaviors within a day or two. However, if your cat continues to avoid food, or if you notice additional symptoms such as vomiting or lethargy, it would be best to consult with a veterinarian to ensure your pet’s health and well-being.
