Sophia did, and she's only 11.
It had been a dream of the spouses to have a lynx. They had consulted with specialists and read about this animal a lot. Once they heard about a little orphan lynx in one zoo and made a serious decision. The Kurilian bobteils adopted the little lynx and took care of it. The lynx still submits to the cats though it’s much bigger. It purrs like a cat but obeys orders like a dog.
By the way, for those who are curious, this is a Eurasian Lynx, found in Russia and other parts of Eurasia, and it is the largest member of the bobtail cat family. The Canadian Lynx is a little smaller, but still bigger than a Bobcat.
