Cats may stop eating after recovering from gastroenteritis. At this time, cat owners can put cat food on the cat's nose and let it lick it to induce the cat to eat. When a cat suffers from gastroenteritis, it will vomit and have diarrhea due to gastrointestinal discomfort. It will become more uncomfortable after eating, making the cat still afraid to eat after the condition improves. At this time, the cat owner must patiently induce the cat to eat.
