I made a very startling discovery last night: I have a HUGE love for Alice in Wonderland. My earliest memory is of being in the middle of reading that book. Perfume oil, eyeshadow, tarot cards -- if it's Alice, I want it.
Last night, I was wondering if Oscar was a Russian Blue or what. (I swear this is all related). So I went and asked Professor Wikipedia. Hmm... The physical characteristics of Russian blues don't seem to fit this guy. But, hey, look, it links to British Blues. Yeah, that totally looks like Oz. The I Can Has Cheezburger kitty is also a British Blue, and he looks a lot like that one, too. And British Blues are a variety of British Shorthair. Mystery solved!
The connection: Tenniel based his artwork for the Cheshire Cat on a British Shorthair. This explains *so much*.
And now, Oscar being VERY VERY ANNOYED at the concept that he may some day be required to get off of the top of the fridge (spoiler because it doesn't want to be resized any smaller):
ETA: (I can't believe I totally accidentally adopted a Cheshire Kitty. Also, that photo makes him look a *lot* thinner than he actually is. He weighs about twenty pounds. I'm going to have to buy another carrier before the next trip to the vet.)
