Could he be related to a Bombay?

We adopted Logan from someone who's indoor/outdoor cat had kittens. He's definitely a mix, but I'd like to learn more about him. He was the tiniest little runt, but he's already noticeably bigger than his sisters. He'll be a year on April 14th, and last week I weighed him in at 12.5 lbs. the picture of him On the stairs is the most recent one, taken today.

could and could.  But the breed is very rare, and Beautiful blackies whom are nice look alikes, - are aplenty.   Thirteen on a douzzin, as the saying is.

The questiob is, why they did bothered to construct such a breed, which is an exact look alike as innumerablr moggies?    My guess is, simply because they could.  

But they are pretty, as yours boy is.
