What does it mean when a cat purrs loudly?

Purring loudly is one way your cat expresses that they’re happy, feline behavior and feeding coach Jennifer Van de Kieft says. “Often, a loud purr shows that your cat is content and happy. Sometimes purring is a self-soothing behavior when a cat is in pain, so be careful to always assess the situation.” In fact, loud purring can help with breathing, pain management, relieving stress and anxiety, and healing.

How is a loud purr different than a regular purr?

A loud purr is just a more vocal version of a regular purr. It sounds stronger due to the increased muscle contractions in a cat’s throat. “A louder purr is showing a more intense state of happiness or enjoyment. Think of it as a regular smile versus a huge smile,” Van de Kieft says. 

Why some cats purr louder than others

There are many reasons why cats purr louder than others. They can stem from feelings of happiness to a cat’s breed. 

Happiness or contentment

If your cat is purring loudly while laying with you, or while you are petting them, it’s a sign that they are supremely happy and content with you. It’s just another way that your cat shows they love you. 

Self-soothing

Loud purring can be a way a cat relieves their anxiety or stress. Purring releases endorphins, so this can be a helpful coping mechanism after (or while) a cat goes through a stressful experience.  

Communication

A cat may purr as a way to communicate with their person. This might involve showing you affection and attention, or it can be a way for them to ask for playtime with you (by purring around their toys). It could also be a way to show that they are hungry. 

Individual cat differences

Purring can change from cat to cat, with variations in pitch, volume, and rhythm of the purrs. All cats have a unique type of purr that’s specific to them, and this may change as they get older. 

Cat breed

Most domesticated cats will purr as a natural characteristic. However, the type of purr can change between breeds. For instance, breeds like Maine Coons and Oriental Shorthairs are said to have louder purrs.

When loud purring could indicate health issues

Sometimes loud purring can indicate health issues for a cat. “Yes, cats can purr to self-soothe when they are injured or not feeling well,” Van de Kieft says. If your cat exhibits other behaviors coupled with loud purring — such as a lack of appetite or fatigue — this might be a sign to call your veterinarian to make sure something else isn’t going on. 

Do cats purr loudly when stressed?

Cats can purr loudly when they are stressed, because it’s a way to soothe themselves. Cats release endorphins when they purr so they feel better when they are purring. 

Can loud purring indicate pain in cats?

Yes, it can. Cats may purr loudly as a way to help repair their bodies after an injury and support their recovery. They release endorphins when they purr, which can be helpful for a cat’s body to relax while they are healing. Be sure to read your cat’s body language for unusual behaviors coupled with loud purring to determine if you should call their veterinarian. 

Bottom line 

• A cat might purr loudly to communicate love, affection, and complete contentment with their pet parent. 

• A loud purr can also be a way for cats to self-soothe if they are stressed, showing pain, or want to communicate. 

• Purrs are unique to each cat, so no two cats have the same purr.
