It's normal for kittens to feel a bit sluggish and lose their appetite after vaccinations. These mild symptoms typically resolve within a day or two and are a sign that the immune system is responding to the vaccine.
- Post-vaccination lethargy is common in kittens.
- Decreased appetite may occur temporarily.
- Monitor your kitten, and if symptoms persist, consult a vet.
After receiving vaccinations, it's not uncommon for a kitten to be sleepier than usual and show little interest in food. These are normal responses as their body gets to work building up its immune defenses. Ensure your kitten has a comfortable and quiet place to rest. However, if lethargy persists beyond 48 hours or your kitten's condition worsens, it may be best to consult a vet for peace of mind.
