Have you ever wondered why your cat makes a vibrating noise? Also called purring, cats make these noises for various reasons, and cat owners love to hear that vibrating sound. Purring is usually associated with being a happy cat, but that’s not the only reason why cats make vibrating noises. In this post, we’ll discuss the five reasons why cats make vibrating noises and what they mean.
The 5 Reasons Why Cats Make A Vibrating Noise
1. They Are Happy
Being happy and content are obvious reasons why cats purr or make “vibrating” sounds. Cat owners love to hear the soft purrs of their feline pals when they stroke their heads or bodies, and it’s a sweet bonding moment that every cat owner cherishes. If your cat looks happy, lying on their back with their eyes half-closed and the tail is mostly still, your cat is happy and content.
2. Your Cat Is Asking for Something or Is Hungry
Some cats will purr when they want something from their owners; for example, your cat may be hungry, or if you have an indoor/outdoor cat, they may want outside. However, domesticated cats have perfected their “mealtime” purr. This purr is different in that a cat will incorporate their normal purring sound with an unpleasant cry or meow. They have learned that humans will be more prone to react by incorporating these two sounds together.
3. Kitten/Mother Connection
Kittens will purr to their mothers. In fact, kittens can start purring when they’re only a few days old. Purring is also another way the mother and kittens can bond. In return, the mother cat will purr back. This sweet communication between mother and kitten signals a strong maternal bond.
4. Relief and Healing
Some cats will purr in an effort to soothe themselves when they are in pain. You can also look at this scenario as a child sucking their thumb to soothe themselves. For cats, purring may have the same effect.
Research indicates that the low-frequency purrs that cats generate are similar to those used in vibrational therapy in human orthopedics. Could a cat’s purrs be helping them to heal? Maybe.
Believe it or not, purring isn’t always a happy occasion. Cats may purr or “vibrate” when they are anxious, and it’s easy to misconstrue the sound as happiness. Your cat may also use purring as a way to cope with stress from pain or anxiety.
5. Your Cat Is Greeting You
Cats have learned how to have their humans wrapped around their paws, and greeting you with soothing purrs is their way of saying, “I’m so happy you’re home! Now, feed and love on me.” After all, what cat owner can resist the soothing sound of soft purrs from their little kitty cat?
How Do Cats Purr?
Now that we know why cats purr or vibrate, let’s dive into how they perform this neat act. Precisely how they purr is still under debate, but researchers have established that cats produce purring sounds through irregular intervals of signals of the laryngeal and diaphragmatic muscles. As air moves past the larynx, the air vibrates and produces a purring sound. Cats can purr during both inhalation and exhalation with a steady pattern and frequency between 25 and 150 hertz.
Conclusion
Cats purr or “vibrate” for various reasons, and the reasons are not always happy. A cat may purr because of pain, stress, giving birth, or, as a kitten, communicating with mom. Purring may also indicate your cat is hungry or simply wants your attention. Let’s not forget it could also be a greeting. Whatever the reason, a purring cat is a soothing sound that most cat owners love to hear, but as soothing as it may be, it’s not always for pleasant reasons.
