― Fyodor Dostoyevsky

“Heaven goes by favor. If it went by merit, you would stay out and your dog would go in.”
― Mark Twain

“Until one has loved an animal, a part of one's soul remains unawakened.”
― Anatole France

“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 A. Montapert
