It's funny, I'm more of a dog person really, but I absolutely love drawing cats. They are just about the most fun thing to sketch. If I feel like drawing but don't really have anything specific I want to draw, I'll usually end up drawing a cat. They just seem to come out of my pencils on their own.
So here's my cat for the day. He's a bit ugly and fat, and I bet he's a drooler, but he was fun to make. Tabby cats are the best for drawing; the lines really help define their bodies, and you've got to love that eye-liner look they so often have.
