You are doing things right. Odds are she will not text you back.
Will just show up trying to give you the keys to take care of the
kitty. I'd let her best friend know through texting that you aren't
available because of your own health to sit for her cat. To please
make sure she has made other arrangements.

And to ask M to make other arrangements also.

And you really appreciate her passing word on.
