If I planned on throwing a dog or cat, I would just get it from PETA because thier shelters kill a higher percentage of incoming animals than any other shelters. Plus the analogy between dog/cat vs octopus is not accurate, as the octopuses were caught for human consumption as food and then sold as such. But this is PETA, so logic doesn't become anyone who represents them.
Plus, why does peta even bother making statements anyway? NOBODY takes those nut-jobs seriously at all. Not to mention that they resort to using violence and terrorist tactics to try to try to make their point. (and thus, IMO should be dealt with as a terrorist organization)
And as eva points out, they are also complete hypocrites, as they are personally responsible for more animal deaths than any other shelter or animal rescue place.
