Collaring is more certain than coloring for identifying black kittens, but there are stripes that show up in bright light. Hetch Hetchy has this grey muzzle that looks like she’s dipped it in grey milk. She’s clean, but looks different from all the others. (She pees differently too, and would benefit from a high sided or covered litter box.) Tahoe has a flash of white on his neck, and he an Merritt are the small ones. Shasta and Anza would be hard to tell apart, except that Shasta’s a little goofier and bouncier; Anza finds toys in everything.
