BBR,
What your holding is a brown bullhead, they are a brown, muddy color.
A white cat has more of a gray color and the barbels right below the chin are white. Their tails are also have more of a fork than the bullhead.
A channel cat also has a forked tail, but lacks the white barbels. The color can vary from very dark to fairly light and can have speckels.
I've caught whites at night through the ice, when the flag goes up you should run, one of them almost spooled me.
