Lucky is one of the secondary antagonists of Stuart Little. He is a Siamese Cat and is one of Smokey's henchmen. He is voiced by Jim Doughan.
Lucky was first seen when he asks Stuart Little where he's going and called him Murray, and was chasing him in the roaster alongside Smokey and Red but they failed to get Stuart as he was going back to his home. He was later seen with Monty, Red and Smokey and was seeing Stuart and Snowbell and then when Snowbell was almost breaking the branch he was standing with Red and Monty and then the branch broke and all 3 of them were screaming and were defeated by Snowball and ended up falling into the water and Red was saying that he'd rather drown and Red escapes from the water with Lucky and Monty. Lucky emerges out of the water all wet and he shakes off his wet fur after he, Red and Monty got defeated. Smokey, Red and Lucky were never mentioned or seen again in the rest of franchise but Monty was seen in the rest of the franchise.
