なめんなよ means ... I don't really know, it's from the 1980s (昭和55年ごろ), very colloquial, showing strong attitude of youngsters (暴走族 - yobs on bikes, so to speak).
The rebel cats with this strong attitude, なめ猫, are from the 1980s. I don't know why. Probably they want their message to reach people in their thirties, who know the なめ猫 series very well.
