Cats purr only when they are happy.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that cats purr only when they are happy?

No. A veterinary-oriented answer states that cats also purr when injured, while giving birth, and even when dying, and a survey of cat-behavior misconceptions treats 'purring means happy' as a myth. Myth-list entries also flag the claim as false, though only in truncated form.
