Lake Forest witch Petunia Patterson enters her four cats in the first Lake Forest Cat Show, even though only three of them are really felines. One of them actually used to be a man before Petunia gave him a love potion that went haywire and changed him into a cat; but he’s a cat she communicates with telepathically. 
The problem is her nemesis Maria Hoodwink and Maria’s mother Estelle also enter a cat in the show. Petunia doesn’t have time to worry about that, though, as poisoned champagne sickens entrants at the show and the grand marshal, Mr. Calhoun, is near death as a result.
Aunt Maxine shows up to save the day—but is her antidote really a cure or another problem? Fortunately, Petunia’s steady beau Noah Becker is on hand to help her solve the case, which becomes even more interesting when his parents show up in town to meet Petunia.
What is needed might be some old fashioned witchcraft, or could that be what caused the problem in the first place?
