You look like an Itty Bitty lion with that impressive mane! Maybe you can convince your sister to trust these kind folks and you can worm you way into their home as you have already conquered their hearts.

To your guardians I want to say that I, too, do TNR and it is especially rewarding when I earn the trust of a feral to the point when he or she decides it is safe (and enjoyable!) to receive human touch. Hope you get the last one spayed/neutered eventually.
