It's normal for your kitten to be sleepier following her FVRCP vaccination. Lethargy and increased sleep often occur as her immune system works in response to the vaccine.
- Most kittens experience mild side effects after vaccinations, including sleepiness.
- Keep an eye on her for any unusual behaviors or symptoms beyond increased sleepiness.
- Ensure she has a comfortable space to rest and recover.
After receiving an FVRCP vaccine, it's common for kittens to exhibit mild lethargy as their bodies adjust. This reaction is similar to what humans might feel after a flu shot. Allow your kitten some time to rest and monitor her closely for any other symptoms, such as signs of pain, swelling at the injection site, or changes in eating or drinking habits, which could warrant a call to your vet.
