After spending his childhood studying, observing and drawing animals, Guillaume became an art agent. Moving between their home in the Loir-et-Cher and Paris where they have a second home, Guillaume and his husband live with about thirty animals... all of them are very unusual.

As children, Nicolas and Nicolas always had animals: dogs, cats, horses, farm animals but also exotic pets (snakes, parrots, monkeys, etc.). Nowadays, they live between Paris and Normandy, surrounded by animals - to whom they speak in French and Dutch.
