I'm guessing, and you can correct me if I'm wrong, but the white gloved hands on cartoon characters might have had their origins back from the days of Vaudeville when comic actors would put on white gloves to make their hands more visible to the Audience. If you can, see if you can find early cartoons by Walt Disney when he drew the likes of his mouse characters with only "Bare" hands. It sure works for cartoon characters though, and as become a sort of "Toon" trademark.

By the way, there was an old Warner Bros. Cartoon pitting Elmer Fudd against a fox who were both stalking Daffy Duck. Fudsy gets the drop on the fox and commands "Hands Up!" When the fox throws his hands into the air it causes his gloves to fly up, and as the gauntlets spin around suspended for a few seconds, it's revealed that that the fox has canine like paws in those gloves.

When I posted this on IB someone, Lukos I think, said it was for the sake of contrast back when B&W film wasn't very good. That makes sense too.

That's neat! I seem to vaguely remember the fox revealing those paws beneath his gloves.

It's very useful
I've got Preston Blair's book

Thanks. It's a great book on drawing and animating toons.

Long ago, Deal Whitley was mentoring other artists and advised them to draw EVERY DAY,
even if it's just a study of your hands.

A corollary to that: everyone has 1,000 bad drawing in them.
The sooner you draw those first 1,000 drawings,
the sooner you advance to the better ones!

I know this is old, but thanks, this will be useful
