Where did you read that she was in the Hamburg cast? She doesn't list Cats in her performance resume. She does mention it in her bio, although this could be referring to the regional production of Cats that she directed.

You can try asking her on the comments section of her website bio (scroll down and you'll see it). Or her public social media / contact info.
