I'm not voting, there isn't options for specific animals.
Cats and dogs are perfectly acceptable to be eaten by other cultures. I however, just as much as I think animals here, think that the animals should be treated with more welfare than they are receiving.
Dolphins however, are a completely different story. Scientists are currently working on proving that these animals are sentient officially and preventing unreasonable killings of these animals, for it would then be 'murder'.
One of the professors at my college is working on it, actually. It's very interesting.
So no, I don't think it's right for them to eat dolphins, especially the endangered species that they are constantly killing for better fish harvesting off of the Japanese coast.
Even though there are thriving numbers of dolphins else ware, the species that they are hunting are NOT thriving, and many are near extinction.
Also, I do think you shouldn't eat one animal because it's better than another, or otherwise it would be acceptable to eat humans, because humans are animals too and they have meat just like every other animal.
