Byron Howard and Rich Moore cite Mabel in a "Deleted Characters" DVD feature, in which she is referred to as "The Old Goat". They report that she had various jobs and different appearances during development, including one point at which she was 'just a screaming old goat', and times she would faint. Finally, she came back as a fellow meter maid.
There is a storyboarded scene with recorded lines, in which she talks to the newly-recruited Judy Hopps at work, inadvertently discouraging her.
Role in the Book
