Yes, that is right. Cat Nights begin tonite August 17th. The term harks back to the days when people believed in witches. You mean they don't now?, lol. An Irish legend says that that a witch could turn into a cat and regain herself eight times, but on the ninth time (August 17), she couldn't change back, hence the saying "A cat has nine lives." Because August is a "yowly" time for cats, this may have initially prompted the speculation about witches on the prowl.
