If the cat has folded ears, it may be a congenital disease. Lack of nutrition in the mother's womb leads to unsteady walking. Normal cats will walk unsteadily due to lack of vitamin B1 and calcium when they grow. At this time, temporary supplementation will cause the cat to walk unsteadily. Recovery; if an adult cat suddenly becomes unsteady in walking, first check whether it is caused by fever or cold. Check the limbs to see if there is any obvious trauma, or whether the head injury causes unsteady walking. Careful observation is required for confirmation.
