I have two cats as well! They're both rescued cats. Shadow is brown and fluffy and an absolute ditz. She also is part ragdoll so she flops over when you pick her up. Alberta is black and white and is deviously smart and clever. She's the one you have to worry about.
Alphonz isn't based off any cats I've had, really. He's more an actual embodiment of my depression and anxiety I've had to deal with. But when it's bundled into a kitten shaped package it really puts it in perspective. I used to be just as fatalistic as he was when my illness was untreated. But for some reason everyone still loves him, even though he's a bastard. Guess he's truly a fitting cat, huh?
I wish I could discuss character theory with someone right now...
