Ask A Vet: Why Does My Cat Trill?

Cats can communicate verbally in many ways. They can meow, purr, chatter and trill.  Cats have vocalizations that seem to have been tailored for use specifically for interaction with humans and not typically with other cats.  In interaction between adult feral cats, many of the sounds and vocalizations that are a part of our daily routine with our cats are absent. Unsocialized adult cats, living wild, might hiss or growl at one another, but seldom meow and almost never trill.

We can instinctively recognize the underlying meaning of hisses and growls, but hopefully seldom experience them with our own cats as they are usually associated with threat or aggression. We already know that our cats are seeking something with a meow and we recognize that a purr is a sound of contentment.

A chatter can be explained by a cat’s anatomy and the presence of special glands on the roof of his mouth. He can chatter to pass scents over the glands and gain more information about something, almost like tasting or smelling. But a trill sound is more like meow and purr in that it is a greeting exchanged between friends. A trill is a sound that is frequently used by mother cats to communicate with her kittens and her kittens know her sounds and are able to recognize her voice. 1

We think that we know what our cats are saying, but scientists have actually looked into the brain areas associated with different vocalizations in the cat to try to better define the positive and negative meanings. It turns out, we are basically right in what we think our cats mean when they vocalize to us.

When your cat trills to you, it is a positive sound. She is greeting you or calling you to her just like she would her kittens or feline family members. You can feel happy knowing that it is a friendly, familiar behavior reserved for very close family. A trill should warm your heart and be considered a greeting filled with love.
