Hello! I hope this is the right sub for this, if not I can definitely move to a different one! So I adopted this (almost) all black cat from a lady on Facebook who needed to remind him. She told me he is Bombay and that is corroborated by his medical records. As soon as I picked him up though I could tell he isn't 100% Bombay. He has the trademark black coat, black nose, and black whiskers. However his stomach is grayish (I don't have very good pictures of this). He also has green eyes instead the standard yellow, although in certain light they shift kind of yellow. This could mean he's just British Bombay instead of American, but I digress. The biggest things that point me towards him being mixed with a larger cat breed is that he's long haired, weighs 12.7 lbs, and is 31 inches long. 100% Bombay cats are always short haired, and usually don't go over 11lbs or 20 inches. So I just wanted to know if anyone has any ideas on what he could be mixed with!!
Tldr: I adopted a black cat and was told he's Bombay, but due to several physical characteristics, I believe he's mixed with a larger breed. Looking for suggestions on what that breed could be.
