Feline Rabies Vaccination Side Effects

Rabies vaccination in cats is recommended on an annual basis; however, some cats can contract mild to severe reactions to the vaccination.

  1. Common Reactions

    • Common side effects to the feline rabies vaccination include a drop in appetite or activity, excessive sneezing, mild fever and swelling at the side of the injection. The conditions typically only last a few days.

    Serious Reactions

    • More serious concerns associated with the virus include an allergic reaction contracted within minutes of the injection or a sarcoma tumor developed weeks to months after the injection. Both reactions are potentially life-threatening.

    Owner Response

    • If you believe your feline has contracted a serious condition as a result of the vaccination, consult your veterinarian immediately. The veterinarian is most qualified to treat or manage the contracted condition.

    Prevention

    • Unfortunately, serious reactions cannot be treated once contracted; therefore, prevention is the most reliable option. Studies have indicated that most reactions seem to occur with the live attenuated vaccine instead of the killed vaccine; therefore, ensure your cat receives the live vaccine.

    Warning

    • Be aware of the vaccinations being administered to your feline and ensure that it only receives vaccinations for which they are at risk of infection; for example, outdoor cats will require more vaccinations than indoor cats due to their increased risk of exposure.
