A cat that refuses to eat or poop for more than ten days after a fall may have internal injuries, such as gastrointestinal injuries, fractures, organ dislocations, internal bleeding, pelvic injuries, etc. It will cause the cat to not eat or eat spicy food. It is best to send the cat in time. Go to the pet hospital for a check-up to avoid life-threatening injuries. If there are no internal injuries, it may be that the cat is frightened or in too much pain, causing the cat to not eat or poop. At this time, the owner needs to accompany the cat to comfort it.
