I'm Thomas O'Malley.
~ Thomas O'Malley
Why, your eyes are like sapphires sparkling so bright. They make the morning radiant and light.
~ Thomas O'Malley to Duchess

Abraham DeLacey Giuseppe Casey Thomas O'Malley (simply known as Thomas O'Malley or just O'Malley) is the male protagonist in Disney's 1970 feature film, The Aristocats.

He is voiced by the late Phil Harris.


Thomas O'Malley comes off as a smooth-talking, streetwise cat who relishes his life of freedom out in the open with no rules and no responsibilities. All of this changes when he meets Duchess for the first time.

He falls in love with Duchess when he first meets her and he quickly starts flirting with and serenading her.

Although he was obviously a little turned off by the fact that Duchess has kittens, but he and the kittens quickly grow on each other and he becomes the kittens's step-father.

Also, when faced with an adversity, O'Malley will indeed rise to the occasion to protect the ones that he cares for and loves.

The Aristocats

In the film, O'Malley appears after Edgar's kidnap plan and tries to get rid of the cats, but is chased off by two dogs. He is instantly attracted to Duchess because of her appearance, but is slightly put off when he learns that she has three children.

However, he soon has a change of heart and helps Duchess and her children get back to Paris safely. During their return to Paris, he becomes smitten with Duchess once again and starts being fond of her children as well as her.

In the big fight scene, he and the Alley cats battle Edgar as he tries to send Duchess and her children to Timbuktu. He saves Duchess and the siblings and becomes a part of the family.
