Cats grow a winter coat during fall when the daylight is reduced. Their winter coat isn’t necessarily influenced by the temperature but mainly by sunlight.
The feline fur protects the cat from external stressors, like chemical damage, skin trauma, ultraviolet light, and against contact with hot surfaces.
Most cats grow winter coats, but naturally, the fullness will vary depending on their breed, the climate of the country they’re living, and the heating conditions of their home.
The seasonal shedding is heavily affected by the hours of daylight outside and, to an extent, by the rise and fall of the outside temperature.
While cats are equipped to withstand cold temperatures, it doesn’t mean that they should and that it’s good for them.
