So many wise people have voiced their concerns about the well-being of animals and the fact that the human species have treated them so horrifically. Here a few quotes that have caught my eye recently:

"It is inexcusable for scientists to torture animals; let them make their experiments on journalists and politicians." Henrik Ebsen

"I have learned from an early age to abjured the use of meat; and the time will come when men such as I will look upon the murder of animals as they now look upon the murder of men."
Leonardo da Vinci

"A forest bird never wants a cage." H. Ebsen

"I gave my beauty and my youth to men. I am going to give my wisdom and experience to animals." Brigitte Bardo

"Animals are reliable, many full of love, true in their affections, predictable in their actions, grateful and loyal. Difficult standards for people to live up to."
Alfred Monapert

And my very favourite:
"Just because an animal is large, it doesn't mean that he doesn't want kindness; however big Tigger seems to be, remember that he wants as much kindness as Roo."
Winnie-the-Pooh
