what breed is my cat?

[Hollistred]

He is Large muscular body with long legs. either foreign or semi foreign.
he has almond shaped yet large eyes with round pupils and medium sized ears that have round tips.
I would say he has high cheek bones and a medium sized muzzle and he likes to meow a lot.
his face looks like an Egyptian Mau but he doesn't have spots. he has a solid gray body with white stomach and chest and legs and a long gray tail with white on the tip.
he is social but not a cuddler
we rescued him and he might be a mut but i can't figure out what breeds he might me mixed with
