When you think about the smoothest cat in the history of cinema, you probably hear that gravelly, honey-soaked baritone before you even see the orange fur. Thomas O’Malley—or Abraham de Lacy Giuseppe Casey Thomas O'Malley, if you’re being formal—is the heartbeat of Disney’s 1970 classic The Aristocats. But the voice of Thomas O'Malley wasn't just some guy in a booth reading lines. It was Phil Harris.
Honestly, Harris was a force of nature. He didn't just play the character; he was the character. If you've ever felt like O'Malley feels suspiciously like Baloo from The Jungle Book or Little John from Robin Hood, you aren't imagining things. That was the Phil Harris magic. He brought a specific brand of 1940s "hipster" swagger into the world of animation at a time when Disney was transitioning into a new, post-Walt era.
Who Was the Man Behind the Voice of Thomas O'Malley?
Phil Harris was a legend long before he ever stepped into a Disney recording studio. Born Wonga Philip Harris in 1904, he started out as a jazz drummer and a big band leader. By the time he became the voice of Thomas O'Malley, he had already spent decades as the wisecracking, hard-drinking, "Southern hipster" sidekick on The Jack Benny Program.
He had this way of talking that felt like a warm hug mixed with a bit of mischief.
It’s a voice that sounds like it’s seen some things but isn’t worried about any of them. That was the vibe the Disney animators wanted for O'Malley. They weren't looking for a traditional "actor" to disappear into a role. They wanted Phil. In fact, the animators often filmed Harris while he recorded his lines so they could capture his facial expressions and the way he moved his hands. When O'Malley leans back with that confident smirk, that’s pure Harris.

The "Three-Peat" of Disney Legends
It is actually pretty rare for a voice actor to play three nearly identical archetypes in three consecutive Disney blockbusters. Yet, Phil Harris pulled it off effortlessly.
- Baloo (The Jungle Book, 1967): This was the breakthrough. Harris convinced Walt Disney to let him ad-lib, which was almost unheard of at the time.
- Thomas O’Malley (The Aristocats, 1970): The smooth-talking alley cat who falls for a high-society feline.
- Little John (Robin Hood, 1973): Basically Baloo in a tunic, right down to the recycled animation frames.
Why the Voice of Thomas O'Malley Almost Didn't Work
There’s a bit of a misconception that everyone at Disney loved the idea of Harris as O’Malley from the start. Some of the "Old Guard" animators felt that using such a recognizable celebrity voice would break the "illusion of life." They worried people wouldn't see a cat; they’d see Phil Harris.
They were wrong.
The chemistry between Harris and Eva Gabor (the voice of Duchess) is what makes the movie work. Gabor had this airy, sophisticated Hungarian accent, while Harris brought the grit of the American streets. It shouldn't have worked. A stray cat from the alleys of Paris speaking with a Southern-fried American drawl? It makes zero sense geographically.

But it works because of the soul Harris put into the performance. When he sings "Thomas O'Malley Cat," you believe he’s the king of the highway. He brought a sense of "cool" to Disney that hadn't really existed before. He wasn't a prince or a hero in the traditional sense. He was a guy who knew where the best jazz was and how to treat a lady.
The International Twist: Romeo vs. O'Malley
Here is something most people totally miss. While the voice of Thomas O'Malley is iconic in English, the character actually changes completely in other languages.
Take the Italian version, for example.
In Italy, Thomas O'Malley is renamed Romeo. Instead of an American alley cat, he’s a "Roman" cat who speaks in a heavy Romanesco dialect. He’s "Er mejo der Colosseo"—the best of the Colosseum. It’s a fascinating pivot. While Phil Harris used jazz and Southern charm to signify "cool" to American audiences, the Italian dubbers used the street-smart reputation of Rome's stray cats to convey the same feeling.

The Legacy of the Alley Cat
Phil Harris passed away in 1995, but his work as the voice of Thomas O'Malley remains a masterclass in personality-driven animation. He proved that you don't need a thousand different voices to be a great voice actor. You just need one voice that is so full of life it can fill a room—or a cinema screen.
He didn't just record lines; he gave the character a philosophy. The "O'Malley way" was about freedom, music, and looking out for your friends. It’s why, over 50 years later, kids still want to be a cat.
What You Should Do Next
If you want to really appreciate the craft behind this role, don't just re-watch the movie. Do these three things to see the "hidden" side of the performance:
- Listen to "The Bare Necessities" and "Thomas O'Malley Cat" back-to-back. You'll hear the subtle shifts in how Harris uses his "scat" singing to define two different animals.
- Look up the Italian "Romeo" version on YouTube. Even if you don't speak Italian, the shift in energy is wild to witness compared to the Harris original.
- Check out old clips of The Jack Benny Program. Hearing Harris play his "hipster" persona in live-action makes you realize how much of his own personality he injected into that orange cat.
There's something timeless about a performance that doesn't try too hard. Phil Harris just showed up, opened his mouth, and let the jazz flow out. That's why he's still the only cat for the job.
