Possibly, cats' paralysis can heal on its own without severe trauma, neurological damage, necrosis, or comminuted fractures. When paralyzed, owners need to prepare a variety of vitamins, calcium and other nutrients for their pets to help their pets replenish their physical strength and rebuild their bones. In addition, the sudden onset of paralysis in cats may also be caused by blood clots. Please go to a nearby hospital to check for details.
