that sounds like a typical russian blue cross

i had one like that, he had a lot of white, and silver, and grey, i called him "Hochi" and he was born in my apartment as i brought the mother in knowing she was pregnant and she was half or quarter russian... this was not long after a lot of ukrainians had showed up in Varna when i was there

i decided to leave Hochi to the neighbourhood also... his two siblings both died very early because i didn't know how important it was to keep them warm, i could have i just didn't know, i was too nervous about mamma being anxious but ... oh well... the two carcasses got stuck in the freezer and when solid were sent out to a sailor's grave in the black sea, poor dears

russian blue cats are a distinct colour but it is a variant of grey, there is also many multicolour breeds, but mostly black and red is definitely almost always female, same as your classic tourtoiseshell
