Istanbul is famous for its many street cats, but Casablanca in Morocco also has thousands of technically homeless cats. And like Istanbul, they are fed and treated well so they are quite friendly to strangers.
Dr. Meryem Imrani runs a veterinary clinic in Casablanca. A cat came to the clinic by himself when he wasn't feeling well. Maybe someone in the neighborhood steered him in the right direction, or maybe he just knew it was the right place. In any case, Imrani treated him for a viral infection and nursed him back to health, and Rico never left. Instead, he settled in as a clinic cat and started taking care of feline patients himself. Rico turned out to be very social and empathetic to clinic patients, at least the cats, calming their fears, grooming them, keeping them company overnight. He even donated his blood at one point. Rico has found his calling.
