Caitlin Ramírez was the daughter of fireman Hector Ramírez. Caitlin was haunted by the fact that her mother had died in childbirth, often suffering nightmares. Having recently moved to Los Angeles, Caitlin began working as an intern at fashion house Forrester Creations, but Hector was opposed to the wealthy Forresters and their lifestyle, so Caitlin lied to Hector about her position; Caitlin also withheld her interest in Thomas Forrester. Soon Hector discovered Caitlin's deception, so she transferred to Logan Designs and connected to her supervisor, Samantha Kelly. On her 17th birthday, Caitlin learned that Samantha was her very much alive mother; Caitlin was happy when Hector and Samantha reunited.

Caitlin hoped to be a fashion designer and got closer to Thomas, who arranged for the Forresters to take a look at her sketches. While dating Thomas, Caitlin fell for his rival, Rick Forrester, and dated them both until Thomas caught Caitlin kissing Rick. Caitlin dumped Thomas for Rick but faced vehement opposition from Hector, who disapproved of his teenaged daughter dating a twice-divorced man in his twenties. After Caitlin's fledgling relationship with Rick fell apart, Caitlin began seeing Thomas again, but Caitlin's hopes were dashed when Thomas ended up only wanting to be friends. Caitlin then disappeared from the canvas, with Hector later mentioning that Caitlin had moved to New York with Samantha.
