Abigail is the orange tabby kitten of Mrs. Halberstadt and her middle-aged son who appeared in the episode iScream On Halloween.
Abigail is known to knock things over in her apartment, claw up people, and run around crazy for no good reason, as most kittens do. This scares Carly, Sam, and Freddie and makes them think there is a ghost in the apartment.
