Sirius' innocent look

This is Sirius. He was a rescue kitty. He was dropped off at my mother in law's work by some police with his 4 other siblings. We picked him up and took him to the vet. They determined he was just 3-4 weeks old. We got him all fixed up with shots etc and I got a few lessons in taking care of such a young kitten. I can't tell you how many times I got peed on.
He's all black with a little white patch under his chin. Like one little star. He also has these random white hairs that grow longer than the rest of his fur. He's a little constellation of fur. So we named him Sirius, the brightest star in the sky; in Canis Major.
