Just because animals cannot speak for themselves doesn't mean we don't have to understand them. Humans, who have higher intellectuality levels than these animals, can put a stop to euthanizing innocent animals. Its just that some are just too ignorant to make an effort, let alone care. I really do not understand people who go to the pet store, buy a cute little kitten/puppy, and just dump them at a shelter once they grow up to be less cuter than before. If you fall into this category of humans, its time for you to WAKE UP. Millions of animals are dying because of people like you.
