When you stroll through the shelters looking for a new cat or kitty most of the times you will not find an indication what breed the cat may be. Any shelter will "guess" what breed a dog may be but cats are usually just found under "domesticated, black and white, long haired". A few shelters will bother to give you a breed guess. Going to a vet is usually no different. They ask for the cat's coat type and color but nowhere does it say: "Breed: ________". Shouldn't cats receive the same kind of recognition?
We have a Blue Russian mix named Cynder. He was a small kitty when we adopted him. He had been returned as being too busy and compassionate. He was exactly what we wanted and he turned out to be a great match for our family. He keeps himself busy when we are not around and when we come home he is right there. He lacks the famous Blue Russian shyness. He will come to anyone who is willing to love him.
