The Naming of Cats

So I'm wondering if (Chocolate) Basil is a dignified enough name for a Maine Coon cat. He weighs about 10lbs now, but I think he'll be about 15lbs when he's all settled in and eating well. Big frame. Check out those paws! (Click for larger image.)

I thought of Orion, but my neighbor, who went with me to adopt him, doesn't really like it.

Ideas and opinions solicited. I'm leaning toward keeping Basil because sometimes first is best, and my experience with cat names is that they never feel quite right, they're just convenient handles. But maybe someone will come up with something that fits better.
