Caught a 37-inch channel cat in the bay once. Big sagging belly -- thing literally looked like a fat old man, needing both a shave and a shower, who somebody had just yanked out of an easy chair. I should've weighed it but I wanted it out of my boat before it slimed anything else.
The smaller cats are excellent on the grill. Best when they still have their spots, <18 inches or so. DNR has consumption advisories on 'em though.
