SHE FOUND THEM!!
Early the following morning, we snuck quietly into Barn Cat Mansion. With a little help from the wish and a whole lot of patience, we waited for Smoke. Thinking our best bet was to wait for her to wake up and come out of somewhere, we sat by the new hay bales.
Eventually, Smoke appeared from between a couple bales on the very bottom of the stack. We finally had a place to look. Pulling bales carefully away, one by one, we uncovered the nest and there they were - two blacks and an orangey cat!!
You gotta love those Fairy Bowl Fairies!! :)
