The Russian Blue Cat
The dense coat of the Russian Blue cat comes in only a few shades of grey. They’re also very friendly, but they want to have their own space, so don’t be upset if your Russian Blue cat rejects your love every now and then.

The Russian Blue cat, on the other hand, will select one particular human to be their “person,” even if they get along with everyone and every animal in your house. It might be you — but it may also be your spouse or one of your children! These cats are also rather pricey, starting at $3,000.
