If an event showing at the Cats Cradle shows general admission then why are their seats and ticket prices ?

I have never been to a sit-down show at the cradle -- I suppose it's possible, though. As others have mentioned, probably best to call the venue.

Call the venue and ask. They are there by 8PM on show days.
