Cats suffering from gastroenteritis will vomit and have diarrhea. Feeding is reduced or not during the treatment period. The cat can eat when its spirit improves and stops vomiting and diarrhea. However, it should be noted that after recovery, the cat should be fed with small meals and frequent meals. You can first feed some canned meat strips to replenish physical strength. After feeding, the cat's condition should be closely observed to avoid recurrence of gastroenteritis.
