I have a kitty that I got from a rescue, and she is a Turkish Van (try google, you will be amazed). They are an anomaly , and occur randomly...tho they are called a breed. They are white and the "cap" and tail markings are a huge factor (they can be black, grey or "red" but I haven't seen a calico), and have extra soft fur (like rabbit fur) because they have no coarse hairs in their coat and their love of water are factors as well. Some have a spot on their back between their shoulder blades called "the thumb print of God" and mine has it. They are sooo loveable. I think Patch might be one!
