Smokey

"The only thing you guys got are big mouths, so shut up and run!"

- Smokey ordering his lackeys. "Not bad for a dead house cat. Say goodnight, Tinkerbell!"

- Smokey preparing to kill Snowbell.

Smokey is the main antagonist of the 1999 movie adaptation Stuart Little.

He was voiced by Chazz Palminteri, who also voiced Buster in Lady and the Tramp II: Scamp's Adventure.

Overview
"How ya doin'? You must be Stuart."

- Smokey and Stuart Little.

He is the leader of a group of Mafia-like alley cats who all desire to eat Stuart. He indeed has a certain air of a crime boss with a Mafia-like personality.

He made a deal with Snowbell that involved getting Stuart out of the house, by cornering the Stouts and forcing them to be pawns in his plan. However, as Mr. and Mrs. Little learn that the Stouts weren't Stuart's real parents, Smokey decided that he and his gang will eat Stuart the same night.

Final battle and defeat
"Beaten by a mouse and his pet cat, what could be worse? (Bark Bark) Oh, nice doggy.  No, NOOOOOO!!!!!"

- Smokey's last words.

Smokey and his gang chased Stuart through the city park and the sewers. Later, Stuart returns to the park to make it his new home. However, Snowbell warned him to get out of there, causing them to be discovered. Afterwards, Smokey decided to kill them both after Snowbell reformed. As he was about to attack Snowbell, Stuart hits him with a tree branch, causing him to fall in the water. In the end, he is attacked by a pack of dogs off screen. It remains unknown (or at least debatable) whether Smokey was killed or just chased away by the dogs.
