It's Christmas Eve and Salem is getting distinctly stir crazy. When Sabrina finds that he's clawed her favorite Christmas sweater, she gets very upset with him. Sabrina decides to go off and meet up with Harvey at The Slicery, and Salem stows away in her shoulder bag. When he emerges and starts chasing a mouse, Sabrina and Salem are ejected from the premises via the back entrance. Sabrina is furious and leaves Salem in a trash can in the alley and goes home. After a while Sabrina starts to get worried when Salem doesn't return home. Meanwhile, Salem has been knocked over and then kidnapped by a small kid on a bicycle named Rex. Salem manages to make a phone call to tell Sabrina and her aunts that he's been kidnapped but he's unable to tell them exactly where he is, so they set off on a door to door search for him.
Joe O'Connor who played Rex's father, played Melissa Joan Hart's father on her previous show, Clarissa Explains It All.
All the doors that were being knocked on belonged to the same house.
Karla DeVito who played Rex's mother is married to Robby Benson who played Sabrina's father in Pilot and Meeting Dad's Girlfriend.
Dave Allen, who plays the manager of The Slicery, is best known for playing the Naked Trucker on the Naked Trucker and T-Bones show and Mr. Kwest in Ned's Declassified School Survival Guide.
The manager of the Slicery only appears in this episode and makes no further appearances on the show, but since he falsely accused of letting Sabrina bring Salem into the restaurant, it's possible that he was fired and Sabrina was let back into the restaurant by the owner in further episodes until the Slicery's last appearance in season 3.
