Formally-Named Pet

"When Dr. Evil gets angry, Mr. Bigglesworth gets upset. And when Mr. Bigglesworth gets upset, people die! "

How do you show that your pet is special? When you want to go above and beyond a normal pet name, a formal title is the easiest way to add some sophistication. He's not just Fluffernutter, he's Mister Fluffernutter! You can usually expect such a pet to be a little lap dog or a pampered kitty. However, they may occasionally be horrible giant scary monsters, so beware.

Often overlaps with Mister Muffykins. The Right-Hand-Cat is often a Formally-Named Pet. Likewise in pet-related cases of Consulting Mister Puppet. How Not to Write A Novel mentions this as something that is overdone.
