Generally, kittens are more likely to suffer from diarrhea after eating too much. Because the kitten’s digestive system is not fully developed, its digestion and absorption ability is relatively poor. If it eats too much, it will cause indigestion and diarrhea. When this happens to a cat, it is best to fast the cat first, then feed it some probiotics to help digestion, and then feed it some wet food the next day. It can usually recover on its own in two or three days.
