Russian Blue vs Siamese
A quiet, reserved, independent shorthair against a slender, constantly talking, clingy one; voice and time alone decide it.
Verdict
Both are intelligent, short-coated, easy-care cats of medium size. The thing that decides it is voice and company. The Russian Blue is quiet, reserved with strangers and scores 4 for independence, so it copes with a workday alone. The Siamese talks constantly, is more active, and scores 1 for independence, so it wants someone home. Choose the Russian Blue for a calm household with a regular routine. Choose the Siamese if you are home often and enjoy a cat that follows you from room to room and answers back.
