Stewie was the first house cat I'd ever had. How was I to know that he is the World's Most Perfect Cat. He doesn't scratch, jump or get into any sort of general naughtiness. He is also very social.
Now Wyatt... Wyatt is a very social cat. Maybe a smidge more so than Stewie. Wyatt is always up in your business and he loves attention from anyone even strangers. These are not run and hide under the bed cats. He is also very tolerant of me hugging, squishing and carrying him around. But naughty. Hoo boy is Wyatt naughty. He zooms around the house, chomps on plants and jumps on the counter. Stewie just stares at him in disbelief.
Wyatt also loves to torment Stewie. Thankfully, as you can see in the Great Box War of 2016 above, Stewie can still put Wyatt in his place.
He is naughty and he knows it.
