I got my clicker starter set today and read the book before starting. I tried to separate one cat, Luna Moth, to start her training, but she was underwhelmed. When I tried just Anya Gray, she was too hungry to focus. And letting 5 cats circle around was hysterical. All in all I thin one of my very timid semi-feral kitties may be the best candidate so far, Persephone really got the target idea. I think she's going to catch on quickly.
