From Larousse Gastronomique
CAT Chat -- Domestic cat whose edible meat has a flavor halfway between that of rabbit and that of hare. Cat's meat has often been eaten in periods of famine or siege. Legend has it that in the cook-shops the cat is often used in the making of rabbit fricassées. Examination of the bones would easily enable one, in case of doubt, to distinguish between the one animal and the other.
Not from Larousse Gastronomique :
Adding one half teaspoon of curry powder to your cat's food every day for the two weeks prior to preparation adds a subtle yet wonderful flavor to the resulting dish.
