Ocicat/Savannah/Bengal?

I have a cat that I found (as a kitten) by a creek. He is orange/cinnamon in colour with spots, and stripes on his legs and tail. He also has a straight nose (vet said a Pharoh nose). My little guy isn't so little, he is heavy (muscle) and larger than an average cat. Also, his hind legs are longer and he walks with a little arch in his back (stealth-like). He loves to play in water, is very active (hunter-like), very intelligent, inquisitive and does not meow like regular cats. His meow sounds like a baby, his own language.
So, my question is would anybody know if my cat is a cross with either a Ocicat/Bengal/ Savannah or a breed that I do not know of?
I have included a link to his pics.

Hi there again..your lovely boy would be considered a Domestic Short Hair (DSH) Orange tabby. Some tabbies can be larger than the typical tabbies as well. DSH tabbies have a variety of breed backgrounds that love water, not only Bengals and Savannahs.

DSH Orange tabbies are so lovable and quite intelligent too. Some orange (also known as ginger) tabbies can have spotted, striped, ticked and swirl patterns in their coat.

Here are more photos of DSH orange tabbies like your baby: http://images.google.com/images?hl=en&q=...

Please note unless a cat specifically came from a breeder with registry papers, all other cats would be considered a domestic short hair or similar.

All of the cross-bred species you referred to require specific breeding techniques that are not a natural occurance in the wild. All of those specialized breeds will be approx 1 and a half times the size of a normal cat-The savannah is bred with a serval. The most sought after savannah is an F-1(1st generation) and sell for 2,000.00 + dollars.
