Chester not only sasses me, he tattles on the others. He'll come running to me: Meow! Meow! Meeeeooowwww! Which means: Wait until you see what Luke/Leonardo did (or is doing)!

He is so unrepentant that if I shake my finger at him, while explaining for the 1,000,000,000th time I don't want him to do something, he'll sniff my finger like: 'Ok, I see that thing you are shaking in my face! Now what?'
