Sadie is a Mackerel Tabby and Sophie is a Persian Tabby. I've had Sadie since she was 3 months for the last year and a half from a rescue. She is very social with us (husband and I), and she visits our neighbor's cat. She is curious about water and loves open access to all the rooms. She sleeps by our feet and follows us around the house. She prefers play as a reward. Recently, Sophie has come to us from the streets. For a feral cat, she is loving and communicative. I did the slow introduction as directed by several articles, yet there is still tension and they have divided territories in our 1 bedroom loft. I'm really hoping by clicker training, I can get Sadie to change some of her hissing behaviors.
