You and Sodo were on a tour together and somehow you snuck kitty onto the bus. So far, it looked like a Blue Russian, and it's head poked out of your shirt. Sodo's head immediately snaps up

"Where did you get the from, " he says, his eyes wide.

"We already have a cat, dear, we don't need another cat," he says but gives the kitty some pats on the head. "No more cats. "

You only needed to give him some time, and name the dog so you would get attached, on purpose.
