Si and Am

"We are Siamese if you please. We are Siamese if you don't please."

- Si and Am

Si and Am are the secondary antagonists from Disney's 15th full-length animated feature film, Lady and the Tramp, and its 2001 sequel, Lady and the Tramp II: Scamp's Adventure. They are a mischievous pair of twin Siamese cats who seek to cause trouble, eat others' food, and incriminate the dog.

In the original film, they were both voiced by the late Peggy Lee. In the sequel, Si was voiced by the late Mary Kay Bergman, and Am was voiced by Tress MacNeille. In House of Mouse and Mickey's House of Villains, they were both voiced by Tress MacNeille (after Mary Kay Bergman's death).

Lady and the Tramp
Si and Am first appeared when their owner, Aunt Sarah, comes to babysit the Brown's new baby. The two emerge from the picnic basket Sarah carried them in, introducing themselves to Lady, then immediately roaming the house, claiming they might "stay for quite a while". They begin destroying the house, tearing up curtains and wrecking furniture. They try to eat the family fish and bird, but Lady comes in to scare them off.

The two then hear the baby crying upstairs, and decide to go and steal some of the baby's milk. Lady, not wanting this to happen, chases them off, causing some destruction. Sarah comes down and investigates, and the two cats fake injury. Sarah pities them and carries them upstairs, while blaming the whole affair on Lady and muzzling her.

Lady and the Tramp II: Scamp's Adventure
Si and Am appear briefly in the 2001 direct-to-video sequel, where Sarah again carries them around in the picnic basket. Scamp wishes he were braver, so he could take on threats such as them.

Later, they are shown at a picnic with Sarah, where they attempt to steal a turkey. However, Scamp rushes by and scares them away.

House of Mouse
Si and Am make several cameo appearances throughout the show, most notably in the episode "Rent Day", where they appear to be rooting and friendly with Aristocats heroes O'Malley and the Alley Cats.

Mickey's House of Villains
Si and Am also appear in the 2002 direct-to-video film, Mickey's House of Villains. They participate in the villains' takeover of the House of Mouse, and later watch the final showdown between Mickey Mouse and Jafar. When Jafar is defeated, they flee with the rest of the villains.

They also appeared in the film's trailer.
