When it comes to cold weather, a ferret can be acclimated in the same manner as a dog or cat. However, ferrets cannot sweat or cool themselves down in any way. Ferrets are at risk of heat stroke at temperatures above 85 degrees. If you have no way of keeping the temperature below that, we suggest cold packs in the ferrets cage, fans and anything else you can do to keep your ferret cool. My Ferret Trembles A Lot.
Ferrets normally tremble for two reasons.
First they often shiver right after waking up, in order to raise their body temperatures. Second, they shake or quiver when excited or frightened. For a young kit, this could be all the time, since everything is new and interesting. For older ferrets, a bath or even a good scolding could prompt trembling. Most often, yes.
