I keep a cat calendar on my desk at work. A few weeks ago there was a cat that looked very similar to Cassis. It was a Burmese. I started reading about Burmese and found that Cassis has many if not all of the personality characteristics. For anyone who has met him, you know that he is extremely social (unlike the other two). He is also very vocal and loves to play “fetch” with toys. He sometimes brings the toy back to you around 20 times!
