A cat’s purr is as classic as the meow. Though many people have no idea what it means when their furry family member makes this sound and that it’s often a cat’s ways of communicating and talking to you. To help you understand your cat better, we rounded up 8 cute, strange and funny reasons cat purr, according to a vet. That way, it can be easier for you to decode what this adorable cat bahavior can mean.

“Purring is a sound produced by a cat’s vocal cords,” says Dr. Chyrle Bonk, DVM, an Embrace Pet Insurance veterinarian contributor. “A cat’s brain signals the vocal cords to rapidly contract and relax at about 30 times per second. As air moves over these vibrating vocal cords, it produces a low-frequency rumbling sound that we know as a purr.”

Feline Physiology 101 aside, cats can say a lot of things with a single purr, and some are contradictory. Dr. Bonk adds that it’s easy to get so used to hearing a cat’s purr, which is why so many pet parents tune it out, but she wants cat moms and dads to tune back in. “A cat purring is something pet owners often take for granted,” Dr. Bonk adds. “It turns into just a sound that your cat emits when they’re lying on your lap or cozying up in a sunbeam. The truth is, purring is a powerful noise that helps convey the way that your cat is feeling.”

Dr. Bonk shares that you can read and respond to your cat’s emotions and needs when you understand when and why a cat purrs. That’s why she’s encouraging Parade Pets readers to check out these common reasons cats purr. Once you know what they are, you and your cat’s bond can be stronger than ever.

8 Reasons Cats Purr, According to a Vet

We often think of a cat’s purr as a sign of love and joy. Yet experts say there are actually many reasons cats purr, and they aren’t always about those good vibrations.

1. They Are Anxious

Dr. Bonk says it’s vital not to assume your cat’s purr is always a sign of happiness. In fact, some pet parents may find it surprising or strange that cats purr when anxious or stressed as it’s a common, but often misunderstood cat behavior.

“There are many causes of why cats purr and one can be when your cat is anxious or stressed,” Dr. Bonk highlights. “Purring is a main form of communication between newborn kittens and their mother, so purring when stressed or anxious can be a cat’s way of self-soothing, reminding them of a time when they were safe and content.”

Understanding this aspect of cat purring meaning can help you respond appropriately and comfort an anxious cat.

2. They Are Happy

Of all the cute, strange, and funny reasons cats purr, happiness is the most well-known. When people search “Why do cats purr when happy?” this is usually the answer they’re expecting. “The classic emotion that we associate with cat purring is joy,” Dr. Bonk shares. “Cats tend to purr as a way to show their happiness and excitement. You may notice your cat does this when they are snuggling on your lap or getting pet.”

3. They Are Simply Content

When cats purr, it can be a cute sign they are content. “You may also find your cat purring when they find the perfect sunbeam to curl up in,” Dr. Bonk says. “Feeling content usually equates to relaxation, which can trigger this cat behavior.” How cute is that?

4. They Are Expressing Their Love

What’s one reason cats purr? To tell you how they feel! “Cats can’t come right out and vocally express their love for you, so purring is the next best thing,” Dr. Bonk says. “Since we associate purring most commonly with happiness, a cat purring when with you should make you think they’re happy to be with you.”

5. They Are Felling Sick

While this reason isn’t cute or funny, it may surprise you if you’ve always believed purring is only a sign of happiness. In fact, many pet parents are shocked to learn the answer to “Do cats purr when sick?” is yes.

“Similar to anxiety, a cat may purr when they’re sick or injured because it helps them self-soothe,” Dr. Bonk explains. She adds that changes in appetite, energy levels, hiding behavior, or litter box habits alongside purring can also signal that something isn’t right as cat purring and illness can sometimes go hand in hand. So if you ever think to yourself, “Why is my cat purring so much?” or “Do cats purr when in pain?” it’s important to look at the full picture so you can help your furbaby feel better.

6. They Are Seeking Attention

If you’ve ever wondered why do cats purr at you, the answer isn’t always mysterious. Sometimes it is funny and is simply about getting your attention. One common myth about cats is that they want to be left alone all the time. In reality, cat purring meaning can often signal a desire for affection, interaction, or play. At times, that’s why cats purr specifically to catch and hold your attention (and score some extra cuddles in the process).

“You’re definitely more likely to give a cat attention if they’re purring than if they’re hissing at you, right?” Dr. Bonk asks (rhetorically). “Purring is a way of drawing people toward a cat because we all want to be a part of a happy play session or comfy snuggle.”

7. They Are Hungry

As a pet parent, you’ve probably thought to yourself, “Why is my cat purring and following me?” Well, hunger might be the reason, because another kind of strange and funny reason cats purr has to do with food, according to Dr. Bonk. In fact, she says some cats develop a specific “solicitation purr” when they’re hungry.

“You draw more flies with honey, so your cat may purr to draw your attention to their food bowl being empty or it getting close to dinner time,” she reports. “Purring may also be accompanied by meowing, rubbing or following you around.”

So if you notice your cat purring near their bowl or around feeding time, it may be a classic case of hungry cat behavior and a polite (and adorable) reminder that dinner is due.

8. They Are Talking to Another Cat

One of the earliest—and cutest—answers to why do cats purr has to do with communication. When it comes to cat purring meaning, one major reason is inter-cat bonding and social signaling.

“Kittens are born deaf and blind, so the only way a mother cat can communicate with their kittens is through touch,” Dr. Bonk reveals. “The low-frequency vibrations of purring can be very soothing and calming, so if a cat wants to communicate peace and comfort with another cat, purring is the perfect way to do so.”

In fact, it’s often a sign of reassurance, safety and positive feline social behavior, which is an important part of cat communication and bonding.
