This artist, Leanne Wildermuth, does oil (color) and graphite (b&w) pet portraits. She's very talented, as a quick glance at her site and online gallery will show. She has some particularly great oil paintings of a GCC.
Pet Portraits - Custom pet paintings by Portrait Artist Leanne Wildermuth
However, you can find other people who do pet portraits-- that's not too unusual. What IS special is that she gives away one free, custom graphite portrait each week! I really admire someone using their talent to brighten the lives of others. You just post a story about your pet (according to her declared subject for the week), along with a photo, and she picks one to draw. Last week, she picked my dear Pippin, who recently passed away. I think she did an excellent job on Pippin's portrait. I love this photo of Pip, because it looks like she's smiling (and it was her favorite toy), but the photo was kind of blurry. The portrait is perfect. Anyway, if you're interested in entering, here's the link:

At some point, when I have some money, I'd love for her to do an oil painting of Pippin, to capture all of her gorgeous colors.
