Your cat can go into shock as a result of severe illness or physical trauma. Shock is caused by any situation that causes a loss of oxygen in the blood and the restriction of blood flow to your cat's vital organs. If you believe that your cat is going into shock or showing any symptoms of shock, take him to the veterinarian immediately.
Shock Symptoms: Hyperventiliation
Unlike dogs, cats do not normally pant or breathe rapidly. If your cat appears to be struggling to breathe, panting or hyperventilating, he may be in shock. The normal respiratory rate for a healthy adult cat is between 20 to 30 breaths per a minute. Calculate your cat's breaths per minute by counting the number of breaths he takes within a 15-second period and multiplying it by four. If the number is significantly higher than 30 and your cat has not been engaging in any type of rigorous physical exercise, your cat is probably in shock and hyperventilating. Hyperventilating is a strong sign of a serious medical problem. Take your cat to the veterinarian immediately if he is hyperventilating or showing any other signs of shock.
Shock Symptoms: Mucous Membranes
Your cat's mucous membranes are located in his gums, lips and inner eyelids. The mucous membranes are normally pink but will appear discolored if your cat is suffering from a medical emergency.
If your cat is in shock then his gums may be any of the following colors:
You can check the color of your cat's gums by lifting his lips up and observing the gums.
Another sign of shock is slow capillary refill time. You can check your cat's capillary refill time by pressing your finger firmly against the gum and holding it there for a second. When you remove your finger from the gum, count how many seconds it takes for the capillary to refill the area with blood and the gum to return to its normal color. The capillaries should take no more than 2 seconds to refill.
Shock Symptoms: Hypothermia
Hypothermia is a fairly common symptom of shock. Hypothermia occurs when your cat's body temperature drops below 99.5 degrees Fahrenheit. The normal body temperature for a cat is between 100.5 and 102.5 degrees Fahrenheit. Symptoms of hypothermia include shivering and being cool to the touch.
Shock Symptoms: Heart Rate and Blood Pressure
Your cat's normal heart rate should be 110 to 130 beats per minute. Shock initially will cause an elevated heart rate but you may see your cat's heart rate and blood pressure drop as the shock progresses into its final stages. The heart rate likely will be inconsistent and irregular as well.
