I have two cats. Both cats seem to understand what is good and bad behavior but one just doesn’t care. Momo understands bad behavior and will do it when we aren’t there. Sencha on the other hand understands bad behavior but will do it right in front of you and doesn’t give a shit. Sometimes when I’m cooking and cutting up chicken he will literally come by and try to grab a piece as I’m cutting it and once I had to play tug of war with him for a piece.
