Kermit
the Frog
Like all good pets he knows not to do stuff I'll kick him in the face for, so yes
You've trained him well.
Alhazred has his three headed cats.
Remembering your history with animals, maybe we should put certain limitations on who can and cannot host animal NPCs.

Theron at one point was going to get a dog resembling a fox that he'd refer to as his familiar (what some D&D character classes call their pets).... I never got around to it though. Image rep would have been from pokemon either Fennekin or Flareon in Theron's reality and a papillon dog in "real life". I may still do that later, depends on what happens this cycle.
As for other pets, two of the Misfits already have some. Kayrentia the Druid has a Dire Bat named Alucard. Keifasar the Dread Necromancer has several but the only two that have appeared enough to be relevant anymore are Neep the Floating Skull and Abduroff the Horse Skeleton.
I think a pet/familiar would work perfect for your style of RPs.
