I saw her this morning- she was lying on one of the cat beds I stuffed under the house yesterday. This is a good sign (they are self-heating beds) My cats didn’t run her off and she is eating the food. Torties are smart and she will figure out that it is safe and soon come out of hiding to say hello. If I push her, I will lose her. But if my two Alphas Fletcher and Bentley haven’t chased her off, this means they accept her into the clowder.
One step at a time – in this case, her not leaving.
