Exactly! All five of ours are of direct lineage. Four are gray tabbys, but the matriarch of the entire clan is a black tuxedo cat. My sister and her family adopted our male’s brother as a kitten, and he’s a black tuxedo cat like his grandma. Doesn’t look a bit like his brother. After eight years, I’m still adjusting to the needs of cats vs. dogs. But, the kids are grown and have families of their own now, I’m on disability, so it’s nice to have the little buggers here to keep me company when the wife isn’t here, even if all they do is sleep and cack up hairballs. LOL!
