It is not uncommon for kittens to experience lethargy after receiving vaccines like the distemper vaccine. Typically, this is a temporary reaction that should pass within a day or so.
- Monitor your kitten for 24–48 hours after vaccination
- Note any additional symptoms, such as vomiting or swelling
- Contact a vet if symptoms worsen or if new symptoms appear
Vaccinations can sometimes cause mild side effects as your kitten's immune system responds to the shot. Feeling tired and less energetic is one of the most common reactions and usually resolves quite quickly. However, if your kitten seems unusually lethargic or other concerning symptoms appear, it may be a good idea to have her checked by a vet to rule out any complications.
