Moira (Catherine O'Hara ) asks "Well, what kind of ailurophobe sends their kitty out to play on such a busy stretch of highway?" An ailurophobe has an extreme or irrational fear of cats, thus would not likely own a cat. An ailurophile loves cats and might send their cat out to play. Questioning whether an ailurophile would send their kitty out to play on a busy highway makes more sense in the context of the scene and dialogue.
