I saw the real Moscow Cats Theatre in 2006 in Skokie, IL and saw them again (so I thought) in 2007, only the show was in a high school auditorium instead of a professional theatre, the show looked cheaper, the cats weren't as focused, the dog wasn't trained...something seemed very odd. Now I know. The real show is incredible, and I hope this doesn't sour them on touring the States.
