Blue cats, historically, achieved wels-like size. There are reliable reports on shipping manifests (which would benefit from downplaying the size of the fish) and from naturalists of 300+ pound fish in the late 1800s! Ictalurus furcatus is a victim of commerical overfishing. A wild fish is lucky to make it 2-3 years before being harvested in most watersheds.
I have kept them before. I absolutely adore them! Blue cats are incredibly active and aware for catfish. They don't sit on the bottom all day like most do; they're always out patrolling. The LOVE current. The more and the stronger, the better. I've found that at tropical temperatures, these fish are voracious predators and honestly, quite dangerous to keep with your expensive tropicals. Their predatory aggression is second to none, though at temperate temps of around 70*, this isn't as much of a problem. It goes hand in hand with their voracious spring and summer feeding.
These fish will be trouble unless you're ready for them. They grow like a RTC, have a temperament like a jau, an appetite like a wels and they swim like an IDS. They may be one of the best secrets of the fishkeeping community, but honestly, its probably for the best that it stays that way.
