Sissy has been with All Cats for quite some time, quite possibly even longer than Mac himself. She had to have all of her teeth removed for dentally hygienic reasons, but that doesn't stop her from being adorable and eating dry cat food. She is always in the lobby to great every person who walks in the door, and I would venture to say that most employees have had to fill out in application while Sissy laid on one arm or the other.
Sissy gives off the persona of everyone's favorite grandmother. She's ready to spoil you rotten, fill you up with treats, and make you feel at peace with yourself. When any of the other in house cats are craving a bite to eat, she's always allowing them to have a few nibbles out of her food dish.
