Wolves of the Forest

Vilkas miške - wolf in the forest

“However much you feed a wolf, it always looks to the forest. We are all wolves of the dense forest of Eternity.”

Animals Never Lie

Excerpt from White Apples by Jonathan Carroll:

White Apples “Here's something you must know and don't forget it—animals never lie. They don't lie, they don't put on disguises, and they are always true to what they are. That's why you can trust them."

“Excuse me, but I do not trust lions. Or bears or snakes—"

"That’s because you want them to be the creatures you imagined as a child. Lions should be the strong but sweet beasts in a Disney cartoon. But they aren't, so when they start acting like lions you're angry at them for not being the fantasy animals you imagined. Real bears don't wear top hats and ride unicycles. Nor do they sleep in bed next to Goldilocks. Human beings force them to do those stupid things in circuses and films or children's books. Sure, some might be more docile or more ferocious than others, but in the end they will always, always be bears. You know you should never should turn your back on a bear. You should never even get near them; it's that simple. They're not being dishonest—you are in your perception of them."

Beginning with What It Can Perceive

Excerpts from Inside of a Dog: What Dogs See, Smell, and Know by Alexandra Horowitz, featured in the The Week Magazine (October 2, 2009):

…forgetting what we think we know is the best way to begin understanding dogs…If we want to understand the life of any animal, we need to know what things are meaningful to it, beginning with what it can perceive—what it can see, hear, smell, or otherwise sense.

Human noses have about 6 million of these receptor sites; beagle noses have more Inside of a Dogthan 300 million. The difference in the smell experience is exponential. Next to a beagle, we are downright anosmic, smelling nothing. We might notice if our coffee’s been sweetened with a teaspoon of sugar; a dog can detect a teaspoon of sugar diluted in a million gallons of water.
What’s this like? Imagine if each detail of our visual world were matched by a corresponding smell. Each petal on a rose may be distinct, having been visited by insects leaving pollen footprints from faraway flowers. What is to us just a single stem actually holds a record of who held it, and when. A burst of chemicals marks where a leaf was torn. Imagine smelling every minute visual detail. That might be the experience of a rose to a dog.

A dog looking around a room does not think he is surrounded by human things; he sees—and smells—dog things.

What we may think an object is for, or what it makes us think of, may or may not match photo by Vegar Abelsnesthe dog’s idea of the object’s function or meaning. Objects are defined by how you can act upon them: what the German biologist Jakob von Uexküll called their “functional tone.” A dog may be indifferent to chairs, but if trained to jump on one, he learns that the chair has a sitting tone: It can be sat upon. But other things that we may identify as chair-like are not so seen by dogs: stools, tables, arms of couches. Stools and tables are in some other category of objects: obstacles, perhaps, in their path toward the eating tone of the kitchen. A ball, a pen, a teddy bear, and a shoe are in some ways equivalent: All are objects that one can get one’s mouth around.

What about a dog’s power of visual and mental perception? Look a dog in the eyes and you get the definite feeling Samanthathat he is looking back. Dogs return our gaze. They are looking at us in the same way that we look at them. Naturally we wonder, is the dog thinking about us the way we are thinking about the dog?

In fact, we are known by our dogs probably far better than we know them. They are the consummate eavesdroppers and Peeping Toms: Let into the privacy of our rooms, they quietly spy on our every move. They know about our comings and goings. They know whom we sleep with, what we eat. We share our homes with uncounted numbers of mice, millipedes, and mites—none bothers to look our way. Dogs, by contrast, watch us from across the room, from the window, and out of the corners of their eyes. Their sight is used to see what we attend to. In some ways, this is similar to us, but in other ways it surpasses human capacity.

Dogs are anthropologists among us. They are students of our behavior. And what makes them especially good anthropologists is that they never tire of attending to minute changes in our expressions, our moods, our outlooks. Unlike us, they don’t become inured to people.

Emotions Come First

From Animals Make Us Human: Creating the Best Life for Animals by Temple Grandin:

Animals Make Us Human I believe that the best way to create good living conditions for any animal, whether it’s a captive animal living in a zoo, a farm animal, or a pet, is to base animal welfare programs on the core emotion systems in the brain. My theory is that the environment animals live in should activate their positive emotions as much as possible, and not activate their negative emotions any more than necessary. If we get the animal’s emotions right, we will have fewer problem behaviors.

That might sound like a radical statement, but some of the research in neuroscience has been showing that emotions drive behavior, and my own thirty-five years of experience working with animals have shown me that this is true. Emotions come first. You have to go back to the brain to understand animal welfare.

Of course, usually — though not always — the more freedom you give an animal to act naturally, the better, because normal behaviors evolved to satisfy the core emotions. When a hen hides to lay her eggs, the hiding behavior turns off fear. But if you can’t give an animal the freedom to act naturally, then you should think about how to satisfy the emotion that motivates the behavior by giving the animal other things to do. Focus on the emotion, not the behavior.

So far, research in animal behavior agrees with the neuroscience research on emotions. A really good study on whether animals have purely behavioral needs was done with gerbils. Gerbils love to dig and tunnel, and a lot of them develop a corner-digging stereotypy when they’re around thirty days old. A stereotypy is an abnormal repetitive behavior (ARB for short), such as a lion or tiger pacing back and forth in its cage for hours on end. Pets and farm animals can develop stereotypies, too. Stereotypies are defined as abnormal behaviors that are repetitive, invariant (lions always pace the exact same path in their cages), and seemingly pointless.

An adult gerbil spends up to 30 percent of its "active time" doing stereotypic digging in the corner of its cage. That would never happen in nature, and many researchers have hypothesized that the reason captive gerbils develop stereotypic digging is that they have a biological need to dig that they can’t express inside a cage.


On the other hand, in nature gerbils don’t dig just to be digging. They dig to create underground tunnels and nests. Once they’ve hollowed out their underground home, they stop digging. Maybe what the gerbil needs is the result of the digging, not the behavior itself. A Swiss psychologist named Christoph Wiedenmayer set up an experiment to find out. He put one set of baby gerbils in a cage with dry sand they could dig in, and another set in a cage with a predug burrow system but nothing soft to dig in. The gerbils in the sand-filled box developed digging stereotypies right away, whereas none of the gerbils in the cage with the burrows did.

That shows that the motivation for a gerbil’s digging stereotypy is a need to hide inside a sheltered space, not a need to dig. The gerbil needs the emotion of feeling safe, not the action of digging. Animals don’t have purely behavioral needs, and if an animal expresses a normal behavior in an abnormal environment, its welfare may be poor. A gerbil that spends 30 percent of its time digging without being able to make a tunnel does not have good welfare.

All animals and people have the same core emotion systems in the brain. Most pet owners probably already believe this, but I find that a lot of executives, plant managers, and even some veterinarians and researchers still don’t believe that animals have emotions. The first thing I tell them is that the same psychiatric medications, such as Prozac, that work for humans also work for animals. Unless you are an expert, when you dissect a pig’s brain it’s difficult to tell the difference between the lower-down parts of the animal’s brain and the lower-down parts of a human brain. Human beings have a much bigger neocortex, but the core emotions aren’t located in the neocortex. They’re in the lower-down part of the brain.

When people are suffering mentally, they want to feel better — they want to stop having bad emotions and start having good emotions. That’s the right goal with animals, too.
