My one-month-old kitten was bought 6 days ago and was fine, but suddenly became listless, walks slowly, is sleepy, and has mild diarrhea — what’s wrong?

Hello, from your description we can tell the kitten shows listlessness, slow walking, sleepiness, and diarrhea. This is very likely a sign of illness, possibly caused by gastrointestinal issues. In addition, because the kitten is very young and has not been vaccinated, the possibility of an infectious disease cannot be ruled out.

It is recommended that you take the kitten to a veterinary hospital promptly for examination to find the cause and apply targeted treatment based on it. Avoid delaying treatment, which could worsen the condition.
