Our cats have fur yes, but even that can't really protect them that well
in cold weather.  My own cat likes to snuggle under the covers with me
in the winter :).  I imagine the Kats would use winter clothing in
addition to any fur.  I remember an episode where it was really hot and
the guys were wearing shorts and shirts.  If it was really how wouldn't
they just not bother wearing clothing?  Or is this considered a taboo in
Megakat City?  oR did Turner just not want "nudity"?
