Hypovolemic Shock in Cats


Hypovolemic shock is a condition that occurs when a cat's blood volume or fluid levels drastically drop and shock can begin rapidly. This medical condition affects the renal, cardiovascular, gastrointestinal and the respiratory systems of the cat. Hypovolemic shock is a serious condition that requires immediate medical attention.




  • Severe weakness
  • Cool feet
  • Poor pulse; a pulse that is difficult to read
  • Very low blood pressure
  • Severe lethargy or inactivity
  • Hyperventilation
  • Respiratory failure
  • Hemorrhage




Extensive vomiting, diarrhea, severe external burns and injury can cause blood and fluid loss. Shock may also be result of exposure to anticoagulant substances, recurring illnesses and hazardous materials.


If your cat has gastrointestinal bleeding, it may be unable to circulate blood volume, which is another way shock can occur.




Your veterinarian will want to determine the underlying cause. Blood tests, including blood gas tests will help to determine electrolyte causes or blood related problems. Imaging can reveal if any cardiac problems have led to the shock. Electrocardiography will identify any issues with your cat's heart. Blood pressure readings are used to determine if the issue is related to the heart's pressure and its ability to circulate blood volume through your cat's body.
