Many people believe that when a cat rubs against you or when you scratch a cat’s head, it purrs out of happiness. Yet purring can mean much more in the same way that human laughs can mean different things based on the context.
Some cats purr when they’re stressed or in pain while other cats purr out of contentment. When listening to your cat purr, make sure you examine the circumstances surrounding the cat to better understand why your cat may be purring.
For the paranoid, perhaps your cat is purring as it deviously plots different ways to kill you. For the less paranoid, your cat could be purring to say it’s hungry.
