Hypothermia in Cats: Causes, Symptoms, Prevention, and Treatment Guide
Hypothermia in Cats: Causes, Symptoms, Prevention, and Treatment Guide
Hypothermia in cats is a condition where the cat's body temperature is significantly lower than normal, and the body is unable to function properly. Unlike frostbite, which is a localized cold injury, hypothermia is caused by a general decrease in body temperature. For cats with a normal body temperature of 37.5 to 39.2°C, a general guideline is:
Mild Hypothermia (32-35°C): This is characterized by lethargy, weakness, and shivering (trembling).
Moderate Hypothermia (28-32°C): Shivering stops, muscles become stiff, heart rate slows (bradycardia), low blood pressure, decreased respiratory rate and depth, and confusion.
Severe Hypothermia (Below 28°C): No heartbeat can be heard, difficulty breathing, coma, dilated pupils, and ultimately death.
Effects of Hypothermia on a Cat's Body:
Cardiovascular System: Decreased cardiac output, leading to arrhythmias and hypotension, increased blood viscosity, and becoming cloudy, in the worst case, random clotting reactions occur throughout the body (Disseminated Intravascular Coagulation).
Respiratory System: Decreased respiratory rate, shallow breathing, due to hypoxia, resulting in hypercapnia, respiratory acidosis, hypoxemia, etc.
Central Nervous System: Due to the above changes, desensitization, impaired consciousness and coma occur, and without appropriate treatment measures, it will lead to death from frostbite. In movies, it is often seen that people who are stranded in the snow mountains slap their cheeks and tell them "Don't sleep!" However, even cats have this feeling when they are in a state of hypothermia.
Causes of Hypothermia in Cats:
1. Small Size: Cats with smaller body size have a larger body surface area per unit weight, making them more prone to heat loss and hypothermia.
2. Kittens and Senior Cats: Kittens and senior cats have thin subcutaneous fat, poor insulation, and their body temperature is more easily lost. Additionally, due to their immature or weakened nervous systems, their ability to regulate body temperature is not as good as adult cats.
3. Weakness/Injury: Weak or injured cats focus their body functions on wound healing, unable to effectively retain heat or generate heat, especially when the cat is bleeding.
4. Prolonged Exposure to Cold: Even healthy adult cats can lose a significant amount of body temperature and develop hypothermia if they are exposed to cold for a long time. For example, when a cat falls into a cold pool or pond and is not rescued for a long time. It is also dangerous if a cat is lost and alone in a snowy place.
5. Chronic Diseases: Cats with chronic diseases, such as hypothyroidism, may have impaired temperature regulation functions and are more prone to hypothermia.
6. Anesthesia/Surgery: Anesthesia can cause a drop in body temperature in cats, especially during surgery, where the exposed abdomen is more prone to heat loss.
Treatment and Prevention of Hypothermia in Cats:
Emergency First Aid for Hypothermia:
Prevent Heat Loss: Move the cat to a warm place, wrap it in a blanket, avoid drafts, and use a warm water bottle or electric heating pad for warmth.
Prevent Excessive Heat Loss: The temperature of the heating device should be controlled at 41-42°C, avoiding excessive heating to cause heat shock.
Keep Airway Open: Clear the cat's nasal passages and mouth of secretions to ensure smooth breathing.
Provide Oxygen: For cats with difficulty breathing, oxygen should be provided promptly.
Fluid Infusion: For cats with severe hypothermia, warm gastric lavage, peritoneal lavage, enema, and warm IV fluid infusion may be needed.
Preventing Hypothermia:
Provide a Warm and Comfortable Environment for Your Cat: Provide a warm cat bed, dress your cat in cold weather, and avoid letting your cat sleep on cold floors.
Control Air Conditioner Temperature: Avoid direct airflow from the air conditioner onto your cat during the summer months.
Avoid Cat Contact with Cold Water: Prevent cats from falling into cold pools or ponds, and avoid letting them outside during rainy or snowy weather.
Regularly Check Your Cat's Health: Regularly take your cat for check-ups to detect and treat chronic diseases that can cause hypothermia.
Summary of Experience:
Hypothermia is a serious condition in cats. If you notice signs of hypothermia in your cat, take immediate action for treatment. Preventing hypothermia is the best approach, pay attention to the cat's living environment, regularly check the cat's health, can effectively reduce the risk of hypothermia.
