Cats are very expressive animals. Not only do they communicate with each other, but they also communicate with humans. Through their facial expressions, bodies, and vocalizations, they are able to express themselves and their needs. Trilling is one of the more unusual sounds that cats make. But what exactly is it? What does it mean, and why do cats do it?

What Is A Trill And What Does It Mean?
Simply put, trilling is a form of vocalization that cats make to express themselves. Cats produce a variety of sounds, from meowing to chirping, purring to hissing. However, unlike many other sounds such as meowing, the trilling sound is made with a closed mouth. When a cat trills, air is pushed through their vocal cords rather than expelled.
The trill is best described as a high-pitched sound, resembling the soft rolling ‘R’s typically associated with Spanish. This sound is often quite short, lasting only one or two seconds. Generally, trilling is associated with positive emotions, while meowing can indicate either positive or negative feelings and usually has a lower pitch, similar to purring.

Reasons Your Cat May Trill
Cats trill for a variety of reasons, typically indicating positive intent. A cat’s tendency to trill can be seen as a sign of comfort, ease, and trust in their owner.
1. Trilling Between Mother and Kitten
Trilling is predominantly used by female cats. When kittens are very young, their mother cat will often trill to cue them to follow her or to grab their attention. Consequently, kittens learn this form of communication early on and tend to mimic it when greeting other animals or people or seeking attention themselves.

2. A Form of Greeting
Adult cats often use trilling as a way to greet their owners or other cats. It serves as an expression of affection and happiness. You may notice your cat trilling as a way to signal that they want you to pet them.

3. Attention Seeking
In addition to affection, trilling can also be a method for your cat to attract your attention.
“If you find that your cat persistently trills at you, they may be seeking your undivided attention,” says Sara Nelms, a pet writer. “It might be an invitation for you to pet her and spend some time together. If your cat continuously looks at you while moving away and trilling, she may be asking you to follow her. Sometimes cats use trilling as a way to show you something.”

4. A Form of Communication
The trilling sound typically indicates a positive emotion or serves as a communication method. Cats may use trilling to communicate with each other and you. If you’re open to it, you can even engage in a conversation with your cat, exchanging trills.

When Is Trilling a Worry?
Generally, you should interpret your cat’s trilling as a positive sign, suggesting they are happy and comfortable around you. However, if your cat is older or entering their senior years, you should monitor their trilling more closely, as it could signal a serious issue.
“In some cases, an increase in your cat’s trilling or sudden excessive trilling can indicate pain, injury, or illness. Try to identify the cause of your cat’s increased trilling and address it. If you’re unsure whether to be concerned, consult a veterinarian,” advises a veterinary expert.

Why Doesn’t My Cat Trill?
Not all cats trill. Trilling often reflects a cat’s personality; livelier, more extroverted cats are more likely to trill, while shyer ones may find it hard to express their emotions. Additionally, some breeds, like Maine Coons, Siamese, or Scottish Folds, are typically more vocal.

Conclusion
Cats have a variety of ways to communicate their needs and express their feelings. Trilling is merely another form of communication and is typically a positive one. Whether your cat is greeting you, seeking attention, or wanting to be petted, take the opportunity to trill back and engage in a playful interaction with your feline friend.
