Generally, cats don't usually have any reaction after receiving the rabies vaccine, as it's a beneficial treatment for them. However, special care should be taken for individual cats. Some cats may experience adverse reactions such as low-grade fever, lethargy, or a slight decrease in appetite. These symptoms usually subside within 1-2 days. If the symptoms persist for an extended period, it is recommended to take the cat to a veterinary hospital for treatment promptly.

Also, some cats may have a strong reaction or be in a sub-healthy state when they are vaccinated, and they may experience vomiting, diarrhea, etc. In such cases, pet owners must pay close attention.
