Sudden limb stiffness and paralysis, inability to bend the knees, foot pads turning purple and black, screaming, twitching and rolling, lower body temperature accompanied by difficulty breathing are all symptoms of cerebral thrombosis in cats. Cerebral thrombosis is an acute disease that spreads slowly. The optimal treatment period is eight hours after the cat is found to have symptoms of cerebral thrombosis. At this time, the cure rate of being sent to the hospital will be greatly improved.
