Stewie

Stewie is an English nickname, a diminutive of Stewart or Stuart, from the Old English stig (house) and weard (guardian), meaning 'house guardian' or 'steward.' The diminutive form has a particular association with the irascible, scheming baby character from the animated series Family Guy.

Stewie is a name with a built-in smirk. Whether or not you are a Family Guy fan, the diminutive form of Stewart has an inherently mischievous quality that works brilliantly on a pet who is clearly plotting something. The Old English root meaning 'house guardian' is technically accurate for almost any pet, but Stewie suggests a guardian who is also extremely opinionated about how the household should be run. Perfect for a cat with an agenda or a small dog with an outsized sense of his own importance.
