Cat Shock
Shock usually follows an accident involving severe injury. It is caused by interference in the blood supply to the brain. Look for shock after car accidents, burns, snakebite, etc. In case of severe injury, treat for shock as a matter of routine, but only after you have checked serious bleeding or applied artificial respiration, as the case demands.
A cat in shock may or may not be conscious. Its eyes will be glassy and it will have a vacant stare. It will shiver or tremble, its breathing will be shallow and irregular, often with long breaths alternating with short gasps. It may also vomit.
A cat in shock loses heat rapidly, and should be kept warm by covering it with a blanket, coat or sweater. If possible, slide a rigor newspaper under its body. Lower its head to assist the flow of blood to the brain. You can do this by placing a rolled coat or blanket under the front part of its body, with its head hanging down. If the cat is conscious, keep it quiet. Get it to the vet as soon as possible.
