Heat Kills!
Protect Your Rabbit From Heatstroke
- Rabbits do not tolerate hot weather well, so providing protection against heatstroke is a must. Rabbits can overheat at temperatures of 26 degrees Celsius and 80 to 82 degrees Fahrenheit, and can die.
- Normal body temperature is 38.5 to 40 C and 101.3 to 104 F.
Rabbits are cooled primarily by respiration, with the ears playing an important part in thermoregulation. In fact, about 80% of heat dissipation occurs through the evaporation of moisture during breathing, with the ears creating a radiator effect.
Rabbits cannot tolerate heat because:
a) they have dense fur coats
b) their only sweat glands are on their lips so they don't perspire well
c) unlike other animals, they cannot pant effectively to dissipate heat
d) they do not drink when they become overheated or dehydrated
Signs of heatstroke include panting, rapid and shallow breathing, weakness, increased or erratic respiratory rate, incoordination, enlarged blood vessels in the ears, and lying flat in a stretched out position. The animal may have convulsions before fading into a coma. Death follows rapidly.
If the rabbit is exhibiting symptoms of heat stress, move him or her to a cool area and place a fan nearby to create a gentle breeze. Mist the ears and body with cool water. Never use ice as this inhibits cooling and never bathe in cold water as the bunny may go into shock. Emergency care may be required so if in doubt, don’t hesitate, go immediately to a veterinarian.
To prevent a tragedy always keep your rabbit safe and protected. This can include keeping their living quarters away from heat sources and out of direct sunlight. Ensure there is always good air movement and that fresh drinking water is provided. Vegetables also help in keeping rabbits hydrated, and be aware that overweight, incapacitated, and aged animals are particularly sensitive.
Transport rabbits in air-conditioned vehicles only, and NEVER leave them in a
vehicle on a warm day, even if the windows are open. Not even for a minute!
This can be fatal.
