Kosher?

So the question came up over pints last night:

Are Gryphon's kosher?

To be clear, I don't know the rules for kosher. I wound up getting the rules backwards (apparently you can't eat something with claws, doesn't chew cud, etc.).

We (the five of us at the table) discussed it off-and-on, then Vicky texted someone from work for the offical word.

The answer is: No. Gryphons are not kosher. No matter how you kill and prepare them, they just aren't.

And odds are they'd be difficult to kill.

We didn't discuss dragons. I already assume they're not kosher.
