Sherman is the rarest of the rare.
He is a cat, a male calico cat, in fact, and you can adopt him.
A male calico cat is the "unicorn" of cats, according to the Mercury News's pets blog. Fewer than "1/10th of 1 percent" of cats are boy calicos, the newspaper reported.
Sherman can be adopted at the Humane Society of Silicon Valley for a very typical price: $175, the adoption price for all pets at the shelter, the newspaper reported.
He's inside the PetCo at 160 East El Camino Real in Sunnyvale.
