Cats Purr When They’re Happy
We all know that when we pat our cats, they start to purr and we think they are happy. Well, it is not correct. According to researches, cats do not purr only when they enjoy while being pet, cats also purr when they are nervous, fearful, stressed, or in pain.

For example, cats create low-frequency vibrations purrs to help their body heal wounds and repair bones. Moreover, kittens use purr to bond more with their mothers or even when they encounter birds.
