Survival of the Fluffiest

I wonder sometimes
Whether cats in warm climes
Put on heavy fur coats when it’s winter.
Though not necessary
Evolutionary biology
Says it’s needed at that time of year.
My cat puts on her
Heavy layer of fur
When the weather begins to get colder.
Fluffs up in the fall
And in spring sheds it all
Never once going out in the weather.
Is it also true that
The Equatorial cat
Has fur coats for both winter and summer?
