Some cats may eat less than usual for a day or two following vaccination.Sneezing (for Intranasal Vaccines):
If your cat received an intranasal vaccine, they might sneeze or have a runny nose temporarily.
These side effects are generally harmless and short-lived, but monitoring your cat closely ensures their comfort and recovery.

While rare, some cats may experience severe side effects after vaccination. Recognizing these symptoms early allows you to seek veterinary care promptly.
Swelling of the Face or Paws:
Sudden swelling could indicate an allergic reaction requiring immediate attention.Difficulty Breathing:
