What is hypothermia & why is it a threat to cats?

Simply put, hypothermia is below-a normal body temperature, and it is usually caused by exposure to cold weather.

Hypothermia happens when the body cannot maintain normal temperature, ‘causing a depression of the central nervous system. It may also affect the heart, blood flow, breathing, and negatively impact the immune system. An irregular heartbeat, trouble breathing, and loss of consciousness to the point of coma may result.’

    Three phases of hypothermia

    • Mild hypothermia is classified as a body temperature of 90 – 99°F (or 32 – 35°C)
    • Moderate hypothermia at 82 – 90°F (28 – 32°C)
    • And severe hypothermia is less than 82°F (28°C)
    Hypothermia and frostbite are serious hazards for cats exposed to the cold winter temperatures.
    Hypothermia and frostbite are serious hazards for cats exposed to the cold winter temperatures.

    So keeping your pet safe during harsh winter weather is important. The best way to manage hypothermia is to avoid it. Always provide warm, dry shelter for pets when they’re outdoors.

    Hypothermia symptoms in your cat

    • Violent shivering, followed by listlessness
    • Weak pulse
    • Lethargy
    • Muscle stiffness
    • Problems breathing
    • Lack of appetite
    • Rectal temperature below 98°F
    • Coma
    • Cardiac arrest

    What you should do if your pet has hypothermia

    • Wrap your pet in a warm blanket or coat. Put blankets and coats in the dryer for a few minutes to warm them up. NEVER USE A HEATING PAD.
    • Bring your pet into a warm room.
    • Give your pet a solution of four teaspoons honey or sugar dissolved in warm water to drink. If the pet is too weak to drink you can also put 1-2 teaspoons of corn syrup on the gums, proving an immediate energy boost.
    • Place warm, towel-wrapped water bottles against your pet’s abdomen or at her armpits and chest, then wrap her in a blanket.
    • Do not use hair dryers, heating pads, or electric blankets to warm up a hypothermic pet as this may result in burns or cause surface blood vessels to dilate, compromising blood flow to vital organs.
    • Call your veterinarian immediately.

    Frostbite

    Frostbite happens when a part of the cat’s body, including their paws, tail, or ears, freezes. Severe winter weather, especially when windy, wet or humid, can lead to frostbite. While frostbite will not kill your kitty, it is very painful, and may require antibiotics to treat any infections, and in severe cases may require amputation.

    Signs of Frostbite

    • Pale, gray, or blue skin at first
    • Red, puffy skin later
    • Pain in ears, tail, or paws when touched
    • Skin that stays cold
    • Shriveled skin

    Frostbite Treatment

    • Apply warm (not hot) water for at least 20 minutes to the frostbitten area. Do not use hair dryers, heating pads, or electric blankets to warm up a frostbitten pet as this may cause burns.
    • Handle the affected areas very carefully; don’t rub or massage them as you could cause permanent damage.
    • Call your vet immediately.

    If you are wondering if it is too cold for your cat to be outside, the answer is to entice your cat to stay in, or come back inside if the cat has insisted on going out. The best place for kitty is safe inside in a warm, cozy bed, or in front of a sunny window, out of harms way. However, sometimes kitty may bolt outside, or there may be a neighborhood or feral cat that is in distress. It’s a subject that we need to keep front and center during the cold winter months.
