I don"t have the foggiest notion. But torties and calicos are my favorite. Calico's are the one with more defined color right.? And tories look more brindle?

Sidney..i found this on cat fanciers..You can check it out if you choose to read all the facts..pretty interesting to me since i have cats///but I persoanl;ly thnk he is a blue cream of some sort...but..read and decide for your self...

If your cat is randomly patched with different colors, you probably have a tortie, patched tabby, or calico.

For cats without white markings:

• A "tortoiseshell" or "tortie" is randomly patched all over with red, black, and cream. The patches may be very mingled, or they may be more distinct.
  
• A "blue-cream" (also called "blue tortie" or or "dilute tortie") is randomly patched all over with blue and cream. This is a soft, pastel color.
  
• A "brown patched tabby" looks almost like autumn leaves, with patches of brown tabby and patches of red tabby. This color is also known as "torbie" because it is a tabby tortie.
  
• A "blue patched tabby" is a soft color with patches of blue tabby and patches of cream tabby.

There is special terminology for tortoiseshells with white markings, depending on how much white they have:

• A "tortoiseshell and white" or "blue-cream and white" has only small white areas. The body has mingled colors.
  
• A "calico" has more white. As a rule, the more white there is on the cat, the larger and more distinct the red and black patches will be. You'll notice that the large black patches are solid black, and the large red patches are actually red tabby.
  
• A "dilute calico" has the same amount of white as a calico, but instead of red and black patches, it has blue and cream patches. The blue patches are solid blue, and the cream patches are cream tabby.
  
• A "patched tabby and white" or "torbie and white" may have any amount of white. A patched tabby with a lot of white, like a calico, has large distinct patches of color, and is sometimes called a "patterned calico," "calico tabby," or "caliby."

Are tortoiseshell cats always female?

Tortoiseshell and related colors (blue-cream, patched tabby, calico etc.) are the result of a sex-linked gene and require two X chromosomes to appear. Generally speaking, these colors will only appear in females. Very rarely, these colors may appear in male cats, but these males are genetically abnormal (they have XXY instead of the normal XY) and are almost always infertile.

I know calicos are always females, I didn't know that about torti's.  Torti's are so beautiful.
