Animals don't think, dude.
Except for apes, most animals are incapable of cognition. So what they 'think' really isn't thinking. If this is about animal cruelty, it may interest you to know that PETA euthanizes pit bulls in the back of the vans it says are for transporting them to good homes/freedom.
I'm all for ethical treatment of animals, but what this video boils down to is just plain creepy and does not convey your point well.
Oh, and try slapping a preloader on the first frame so it doesn't endlessly loop.
I'm interested to know what prompted this.
