Why do Cats Purr?

The Top 4 Reasons for That Distinctive Sound

Every cat person knows it - the deep, blissful rumble of a well-contented kitty. Everyone assumes that a cat’s purr is the same as a smile or laugh on a human. However, that’s only part of the story. Today, scientists and veterinarians believe there are many reasons why cats purr - and it’s not just a way of expressing their love for you.

Curious? Keep reading to find out the top reasons that your cat is treating you to purrs.

1. Your cat is happy or contentIt deserves to be stated: many times, the reason why your cat is purring is because he or she is pleased and content. Cats are often observed purring in pleasant situations, like mama cats nursing their young, friendly cats grooming each other, or household cats being petted by their favorite humans. 

2. Your cat is self-soothingHave you ever found yourself laughing or crying after a physical or emotional upset? These behaviors can help you calm down and regain emotional equilibrium. Purring may fill the same role for cats. Veterinarians believe that cats sometimes purr in an attempt to feel better if they’re sick, injured, or even hungry. 

3. Your cat is trying to soothe someone elseCats don’t just purr when they’re upset or injured - they may also purr when another creature they care about is upset or in need of medical or veterinary care. Cats have been observed cuddling close to injured or ill cats and purring in an attempt to soothe them, and sometimes they’ll even do this for humans. However, there isn’t much scientific evidence to explain this behavior fully.

4. Your cat is building tissue and bone strengthMost cats purr at a frequency of 26 Hertz, which has been linked to regenerating tissue and bones. Wild cats often spend much of their days laying around waiting for a hunt - purring might help their bones and muscles stay strong even when they’re not active. Your cat might have retained this behavior from his or her wild ancestors.

So, why is your cat purring?

When it comes to decoding a particular cat’s purr, everything depends on context. A cat kneading your lap, slow-blinking at you, and settling in for lots of love is probably purring at you because she’s happy. A cat purring insistently around dinner time is probably politely asking you to hurry up and fill the dish already. A cat settled in next to his lethargic brother and purring may be trying to help that cat feel better - which you should take as a signal to bring the lethargic cat to the vet.
