Cuddling your cat on the couch with a blanket and a book or the television sounds idyllic, doesn’t it? But what if your cat purrs when they sleep? If they’re noisy purrers, you might have to turn the volume up on the television if you stand a chance of hearing what’s happening on your show!
Cats are able to purr in their sleep because they sleep very lightly. Cats usually purr when they are content and happy, but they can also purr when they are sick or in pain. Sudden snoring, which might sound like purring, can be the sign of an illness or other problem.

When your cat is purring noisily and disturbing you, you might find yourself thinking, “Well they can’t purr forever, they’ll fall asleep soon.” Sometimes, though, the purring seems endless, even when your cat is sleeping. Short of buying noise-canceling headphones, there’s not much you can do about your cat’s purring! Let’s find out why cats purr when they sleep.

What Is Purring?
Purring is a special vocalization made by cats. The sound originates in their larynx (throat) near their vocal cords and is caused by vibrations of the bones and muscles during inhalation and exhalation.
Purring forms an important part of bonding, communication, and reassurance in domestic cats as well as some other cats in the wild, like cheetahs and cougars. Big cats like lions and tigers can’t purr, but they can roar—a sound that domestic cats can’t make.

Why Do Cats Purr When They Sleep?
Humans might snore and some people might even talk in their sleep, but it’s still hard to imagine how cats can purr and sleep at the same time. Here are some of the reasons why:
1. They Don’t Sleep Very Deeply
Humans go through different phases of sleep including the deep sleep phase and the rapid eye movement phase (where we do most of our dreaming). Although it’s likely that cats also have different sleep phases, their sleep is generally much lighter than ours. This means that they can purr, stretch, roll over, and even open their eyes at the slightest noise or movement.

2. They’re Self-Soothing
Many cat owners assume that cats purr because they are happy, content, or relaxed. However, although cats do purr for many positive reasons, there are also negative reasons for purring.
Cats will purr to reassure themselves when they’re feeling unwell, uncertain, painful, or anxious. Just like babies might need a lullaby or white noise to drift off to sleep, purring can be healing, helping your cat calm themselves enough to join the land of nod.

3. They’re Content
Purring cats are widely recognized as happy cats, and thankfully that is very often the case. So, if your feline is curled up next to you, purring away while they sleep, it’s likely that they’re feeling safe, content, and loved.
It’s also a sign of affection. Even kittens purr when they sleep, as they snuggle into the mother cat and their littermates with a belly full of milk.

4. They’re Feeling Unwell
As we previously mentioned, purring isn’t always a good thing. If your cat is purring while they sleep it could mean that they’re sick. The rest of their behavior might give you a clue about whether there’s something wrong.
If they’re eating well, interacting with you normally, and generally seem happy, they probably are. However, if they’re hiding away, don’t want to be touched, or they’re not sticking to their usual eating, drinking, and toileting routine, there could be something wrong.

5. They’re In Pain
By the same token, if your cat is showing signs of pain as well as purring, it could be that they’re purring because they’re sore. Look out for limping, licking at wounds, pawing at their face, or a hunched posture. These can all be signs of pain.

6. They’re Anxious
If your cat seems to be withdrawing, if they’re peeing around the house or pulling their fur out, they might be anxious. Although anxiety doesn’t seem to be a logical reason to purr, the purring can actually reassure your cat and make them feel better.

7. They’re Not Purring, They’re Snoring
It’s really important not to confuse purring with snoring. Both can be normal, but if your cat suddenly starts making noise when they sleep it could be a sign that something is wrong.
Sudden snoring or noisy breathing can be caused by inflammation or swelling within the nose, mouth, or throat. It could also be an indication of a growth like a polyp or a tumor, an allergy, or a respiratory infection.
If you notice your cat’s purring or snoring while they sleep when they didn’t before, get a vet’s opinion in case there’s an underlying health condition causing it.

Why Don’t Cats Sleep Deeply?
As humans, we can sleep soundly in our homes feeling safe and free from threats. After all, our doors are (hopefully!) locked, and we have police on call to deal with any incidents. A cat’s life is very different. Although you might think that a cat’s life is very easy, their instinct tells them they need to be always on guard and aware of any potential threats.
Being on high alert isn’t easy, especially if you want to get some sleep. So, unless a cat feels super safe and secure, they’ll doze in a very light sleep so that they can quickly respond to any predators or threats that might appear.

Most importantly, book an appointment with your veterinarian if you have any concerns.
