Aren't they sweet? They don't know that cats and dogs don't get along!
I've Picniked this photo. (Careful, it's addictive!) I think that rendering them in pencil equalizes them visually and just looks really, really neat. In colour, my pusscat is a lilac point Siamese...whites and mauves and blue eyes, while Nokey Dog is sable, black and white and brown eyed. I like how removing the colours brings out their faces while sort of blending the two of them together in a lovey-dovey way.
