All I can say is GO!!
It is a wonderful musical and even your non-cat friends will enjoy it. The dancers did such a good job of doing catlike things in the background (opening jaws wide, lifting paws from the floor). You may want to read TS Eliot's book of practical cats before you see it.
It was such a tiny theater, only holds about 200 people. We were front and center and it was almost like being onstage with them. You could hear every grunt and foot movement. What was also neat (at least I liked it) is that if you are in a big theater and far away, the sounds reaches you as a chorus. But if you are up front and it is a small theater, you hear the individual voices as they go dancing past.
Many of the performers had been on the US tour of Cats, a few were local and there was the one guy who had done the role on Broadway so overall it was outstanding.
But man, I gotta lose weight!!
Those people were in such great shape, I don't see how you can dance like that let alone sing at the same time!.
