Loki, AKA Bitey Whitey, is a 2009 model. So that means he's... going to be 2 or so in the next few months. When I first acquired him, some of the names tossed around, like "X head", were based on the big grey X on his head.
X head in an amazon.com book box, spring 2009
X head in a waste basket, Kiki for scale, 2009, inspiring the name Garbage Cat
Garbage Cat in the kitchen trash, 2009, inspiring me to always close the lid, even if I'm just taking 2 steps back into the kitchen to pick up more un-compostables to dispose of.
Now Loki is as long as Kiki, though not as tall or as wide, and interestingly, he is completely white - there isn't even a single grey strand of fur on his head. Thus the continuance of the name Bitey Whitey.
