It's common for kittens to experience a mild reaction after receiving their vaccinations, including lethargy and a decreased appetite.
- Some fatigue and reduced eating can be normal responses post-vaccination.
- These symptoms usually resolve within 24-48 hours.
- Monitor her condition, and contact a vet if symptoms persist or worsen.
Vaccinations can sometimes cause mild side effects as your kitten's body builds immunity. It's not unusual for them to feel a bit under the weather for a day or two. Make sure she has a comfortable place to rest and keep offering her favorite food and fresh water to encourage eating. Keep a watchful eye on her, and don't hesitate to contact a vet if you're concerned about her condition.
