It's possible you're thinking of another actress, or perhaps you are thinking of a different production that she may have been involved in.
To help you find the right information, could you please tell me:
* Which Kim Rhodes are you thinking of? There are a few actresses with that name.
* Are you thinking of a specific production of "Cats"? (e.g., a specific year, city, or theater)
With more information, I can help you find the answer you're looking for!
