Gabby

Gabby’s Role in The Cat in the Hat

Adapted from Dr. Seuss’s 1957 classic, the film updates the original’s unnamed girl known as Sally in earlier adaptations into Gabby, a teenager struggling alongside her younger brother Sebastian after a difficult relocation to a new town. She is the Cat’s primary target of intervention: an assignment handed down by the I.I.I.I. (Institute for the Institution of Imagination and Inspiration, LLC) to shake two miserable kids out of their malaise. Gabby is no passive participant in the mayhem, though. When the hat-wearing intruder barges in uninvited and yells in their faces, she hits him with a pepper spray blast before Sebastian can even finish shouting “stranger danger” a joke that perfectly captures her guarded, self-sufficient nature. Getting her to actually embrace the Cat’s brand of joy is the film’s central challenge, and the entire arc depends on her reluctant, hard-won openness to wonder.

Who Voices Gabby in The Cat in the Hat?

Xochitl Gomez lends her voice to Gabby in this 2026 Warner Bros. Pictures Animation film. Gomez first made her mark on the global stage as America Chavez in Doctor Strange in the Multiverse of Madness (2022), the Marvel Cinematic Universe entry where she played a dimension-hopping teenager with uncontrollable star-shaped portal abilities. Her background over two dozen youth musical theater productions before age 12 and a breakout run as Dawn Schafer on Netflix’s The Baby-Sitters Club has always pointed toward this kind of vocally alive, emotionally layered work. Casting a young Latina actress with Gomez’s natural screen energy to voice a modernized, sharper-edged version of the original’s girl character is one of the film’s most telling creative choices.
