There are many people who have undergone great suffering who seem to possess knowledge of the deepest recesses of human emotion unavailable to the rest of us. They may want to impart it, but we often cannot hear. Strangely enough, farm animals strike me in the same way.

Many years ago, when I was merely a vegetarian, I met the great Cesar Chavez, and he said to me: "If you are interested in preventing animal suffering, the first thing you should give up is eggs and milk, because the animals who produce those foods lead the most unhappy lives. You would do better to eat meat and stop eating eggs and dairy products." I was shocked, since I had no intention of eating meat but had never thought of giving up eggs or dairy products. But when I looked into it I realized he was right, and now, years later, after I have studied the matter up close, I know for certain that he was completely correct about the cruel treatment of the animals raised for such products. The advantages of a vegan diet are enormous for our health, for the environment, for the animals themselves.

Rats and mice are not generally regarded as pets, but as pests; they have few defenders. Yet the pain a rat or a mouse feels is every bit as real as that of any pet. In laboratories, they suffer, as anybody who has heard them moan, cry, whimper and even scream knows. The experimenters dissimulate about this by insisting that they are merely vocalising. Descartes lives on.

Many people feel more complete with a cat in their life, and I would not be surprised if cats felt the same way about us. I know that if I disappeared from the lives of my five cats, they would not be as happy as before. I know, because they wait for me to go on walks along the beach, though they could perfectly well go on their own. When I am with them, they react in such a strong way, gamboling, racing ahead of me, and then flopping down in my path, that it is obvious they derive great pleasure from my company. I find it hard to believe, though, that they could possibly enjoy my company as much as I enjoy theirs. This is not surprising: we domesticated cats for our benefit. While they get something from it, we probably got the better deal.
