Your rat gallery is just adorable, and wonderfully shot! I think in terms of sheer cuteness, this one wins. That tispy look, that you caught at just the right moment, gives me fuzzies.
Do you think it would be alright for me to draw this image, as an animal practice? I've been looking to add more critters to my belt, and the fur and whiskers on this one would be perfect. I would, of course, credit you. If you'd prefer I not, that's fine.
