I'd say the best is when I was in Africa, I saw a hippo in a house. Someone had a pet hippo. And they're meant to be one of the most dangerous animals on the planet, and they had one that was sort of just wandering in and out of their house, just sort of roaming about.
Scientists should not do animal testing if there is any alternative, but subject to that, I would support it on grounds of the medical benefits.
