5. Be sure to give your ferret the right temperature and humidity levels
Ferrets are unable to take high temperatures – they aren’t built to lose heat through sweating. Winters can also be dangerous, when the humidity is high. If the heat outside goes above 90°F, you need to make sure to put your ferret in an air-conditioned room indoors. If you don’t have air conditioning, you need to somehow create a cool area for your ferret – say, by putting its cage in the basement.
