When taking a ferret’s rectal body temperature, the range that is considered normal is between 99 degrees Fahrenheit and 104 degrees Fahrenheit, although the average temperature measures around 101.9 degrees Fahrenheit. For having high normal temperatures, they don’t tolerate heat all that well. Anyone who has a ferret as a pet needs to take very careful steps to ensure that their ferret doesn’t get heatstroke during the summer.
If a ferret is having heat trouble, they might be lying on the floor or ground, with their mouth open. Ferrets can’t effectively cool down by themselves; they’re built for cold weather. When a ferret salivates more than usual, goes limp, has a dark pink nose, red foot pads, or pants, it is time to get it inside and cool it down.
