Cat Trilling: Why It Happens and What Your Cat Is Telling You

Let’s talk about cat trilling — from why only certain cats make this noise to how cats use it to communicate, and more.

It happens every day. I get home and I’m greeted with a “rrroooowe, brrring, brupppp, brupppp!” or some variation of similar noises. No, I don’t have an old-fashioned telephone or my iPhone set to some nostalgic ring. The sound — commonly known as cat trilling — is coming from my small calico cat, Merritt, as she excitedly greets me and seems to chat me up about her day.

My other cat, Gabby, is excited to see me but remains silent as Merritt trills away. Maybe he’ll give me a soft purr as he cranes his head up for a head pet but that’s about it. So, why does only one of my cats do this cat trilling noise? And why do cats make this funny noise in the first place?

Why do cats trill?

I had a hunch that cat trilling was a positive sound. Not only does Merritt trill when I get home, she trills when she sees or hears her treat bag or food. To be sure, I confirmed with Dr. Sasha Gibbons of Just Cats Veterinary Hospital in Stamford, Connecticut. “Trilling is a high-pitched, chirp-like noise made by cats as a greeting to people or other cats. It is associated with a positive, welcoming vibe,” she says.

But what about other times that cats trill?

According to The Humane Society of the United States, cat trills are how mama cats get their kittens to pay attention or follow them. Merritt is one sassy diva of a cat who loves the spotlight and being around others. How dare any guest not admire her or let her rub their leg in greeting! If I sit down and Merritt is in the general vicinity, I know I should plan on staying put for the next 20 minutes. She will be in my lap, head-butting and purring away for all of the attention!

So, it makes sense that she would trill, especially in situations where she’s telling us humans to pay attention (!!!). The treat trills I previously mentioned are great examples of the “follow me” (“Hey human, I’m right over here!”) and “pay attention” (“Do NOT feed the treat to my brother first — even though he is silently waiting like a complete angel!”) commands.

How is cat trilling different from cat meowing?

Why wouldn’t cats just meow for attention or to say hello? Gabby, my cat who is a bit quieter and doesn’t trill, meows for attention, but the sort of attention he wants is usually negative. Case in point: Gabby will sit by our closed basement door and meow until I come to him. He’s not supposed to be in our basement but he’s escaped down there a few times. And — naughty and smart as he is — he wants to go back.

“Meowing is done with the mouth open, whereas trilling noises are made with the mouth closed,” Dr. Gibbons explains. “Trilling is almost always a positive noise, whereas meowing can have positive or negative connotations.”

For those who haven’t heard it, what does cat trilling sound like?

 

If my rotary phone-esque “brrring” and the common “rrroooowe” descriptions don’t do cat trilling justice, think of it as a lot of high-pitched, rolled, Spanish-style “Rs.” For a really good demonstration, let’s talk to Merritt herself!*

How do cats make the trilling sound, anyway?

As all cat lovers know, cat anatomy is a fascinating thing. So, what exactly happens when cats make this odd noise?

“The trill is a high-pitched sound because it is made by cats pushing air through their ‘voice box’ with their mouths closed so the air is not being expelled,” Dr. Gibbons says.

Why do some cats trill and others don’t?

“The amount of trilling varies with personality,” Dr. Gibbons says. “Some cats are shy or apprehensive so they do not trill.”

This aligns perfectly with my two cats. Gabby is a quiet, older kitty who shies away from too much attention, whereas Merritt is a younger cat who loves to be the center of attention.

Am I only the one who trills back at my cat — and can she understand me?

 

I can’t be the only cat lady who has conversations “in cat” with my kitty — see the video above. Since Merritt is so chatty, I started to make similar trilling noises back to her. Sometimes, I’ll ask her a question and she will promptly respond in the exact tone of the answer I’d expect.

Me: “Merritt, do you like your new toy?”
Merritt: :::Happy trilling sound:::

Me: “Merritt, where’s Gabby?”
Merritt: :::Confused trilling sound that I take to mean ‘I dunno’:::

Before you think I’m nutty, here’s a doctor’s opinion confirming that she understands me — sort of! “Trilling can be used for cats to communicate with other cats or with people,” Dr. Gibbons says. “She can definitely understand your tone and that you are great pals!”

So, trill away, cat ladies and gentleman. It may be the closest thing we have to talking to our cats for now!

Tell us: Do you have a cat who trills? What does his or her trill sound like to you? When does your cat trill?
