However, in this case the window of opportunity has more or less passed, gaining a positive ID would be very difficult to attain certainty this is her cat, and still no way of communication. This person is not going to know due to these circumstances.
The PPs have or are about to turn 3 very soon. A pic for each year of their life so far.
The last pic is the day the feral kittens arrived here, too scared to come out of the basket. Now I have both of them bouncing around on the bed, making sure I wake up in time for their breakfast.

And the top pic is them watching out the window, waiting for birthday presents to be delivered.
