She will start paying attention to you if she is ever dependent on you. My mom’s cat would ignore me most of the time if my mom was around. But if mom was on a trip and I was cat sitting, it was a different story. The minute the cat realized she was stuck with me she warmed up to me and would even cuddle on my lap. She even pointedly ignored my mother for the first half hour she was home if I was there. She was punishing my mother for having left her. Once she forgave my mother she started ignoring me again.
