Ferrets are inquisitive, fearless, and capable of getting into places that you never imagined. Ferrets should not be left in a cage for an extended period of time. High heat and humidity can be a killer. Additionally, a small cat sized carrier should be purchased for trips to the vet. Never leave your ferret in the car on a hot day and always provide a hanging water bottle in the carrier during transport.
Ferrets are very clever.
They can recognize their name and with patience be taught to respond to verbal commands. Many ferrets have learned a few simple tricks. For this reason, neutering is strongly recommended. If a female is not brought out of heat, she can develop an infection due to the enlargement of the vulva. There are new ferret diets appearing on the market all the time, but the ones that are fish based are not liked very well by ferrets.
