The wildcat has the LG or LT on the right side of the formation. I did see one of Henning's famous spread offenses with a direct snap but the first drive was all wild cat.
No. You are incorrect. The wild cat is basically the single wing. Ricky must streak pre-snap towards Ronnie. The line has nothing to do with it. That's just usually part of it and is called an unbalanced line. If there is no streaking.. there is no wild cat. It's just a direct snap.
The wildcat is an offensive formation rather than an overall offensive philosophy or 'offense' (for example, a spread-option offense might use the wildcat formation to keep the defense guessing, or a West Coast offense may use the power-I formation to threaten a powerful run attack). When the wildcat formation is deployed, it uses the same pre-snap motion coming across the formation on every play and every play initially looks like a sweep behind zone blocking.
