I was unaware that the issue of cetaceans had been decided. They're certainly intelligent, but are they more intelligent than chimps? This is very hard to evaluate, given that we humans really don't know how to test for intelligence in animals other than fellow primates.Actually, scientists have determined after decades of research that cetaceans are the second smartest creatures on the planet. In fact, some scientists argue that cetaceans should be granted special rights as 'non-human persons' due to their observed intelligence.
Also, there are plenty of campaigns against cruelty in agriculture.
