He is beautiful!! Spike looks like a hooded rat, but I usually see hooded rats with either a beige/tan head area or dark brown/black, but Spike has a gorgeous russian blue type colored gray fur on his hood. Very pretty! Is there such a thing as a Russian Blue hooded rat? Anyone have any opinions? He is a cutie by the way! Hooray for you deciding to get him from the Humane Society, awesome. I bet he is a grateful boy.
