Target brushpiles for big cats?

Been doing mostly crappie fishing this year with pretty good success on brush piles. I've convinced myself that big flatheads and blues would hang out around brushpiles to catch a stray crappie.

Anybody every targeted big cats like this?

Seems like a no brainer....

It's what I do on the Tennessee River. Actually it's trees that have fallen into the river. Lots of them now since the February flood.
