Role in the Movie
She is first seen when Ratigan is mad at his henchman, Bartholomew, for accidentally calling him a rat so he throws him outside and summons her with a bell. Bartholomew is heavily drunk, so he doesn't notice her walking up behind him. She catches him and eats him.
Later, after Fidget tells Ratigan that he lost the list he gave him, he sends Felicia after him and she tries to eat him, but Ratigan figures he could still be useful, so he has her spit him out. When the henchmen arrive at the queen's palace, they use her as a vehicle and Fidget tries to feed the queen to her.
Later, she's interrupted by Basil's dog, Toby, who chases her away. She manages to escape from him and sticks her tongue out at him as she escapes over a fence only to be attacked by the royal guard dogs; bits of fur and the bow in her hair were seen flying through the air. It is unknown whether or not she survived.
- She was voiced by Frank Welker.
