They Have Opposable Thumbs
Which makes them the perfect tools for such tasks as opening doors, getting the lids off of cat food cans, changing television stations and other activities that we, despite our other obvious advantages, find difficult to do ourselves. True, chimps, orangutans and lemurs also have opposable thumbs, but they are nowhere as easy to train.

2. How And When to Get Your Human's Attention
Humans often erroneously assume that there are other, more important activities than taking care of your immediate needs, such as conducting business, spending time with their families or even sleeping.

Though this is dreadfully inconvenient, you can make this work to your advantage by pestering your human at the moment it is the busiest. It is usually so flustered that it will do whatever you want it to do, just to get you out of its hair. Not coincidentally, human teenagers follow this same practice.

Here are some tried and true methods of getting your human to do what you want:

Sitting on paper: An oldie but a goodie. If a human has paper in front of it, chances are good it's something they assume is more important than you. They will often offer you a snack to lure you away. Establish your supremacy over this wood pulp product at every opportunity. This practice also works well with computer keyboards, remote controls, car keys and small children.

Waking your human at odd hours: A cat's golden time is between 3:30 and 4:30 in the morning. If you paw at your human's sleeping face during this time, you have a better than even chance that it will get up and, in an incoherent haze, do exactly what you want. You may actually have to scratch deep sleepers to get their attention remember to vary the scratch site to keep the human from getting suspicious.

3. Punishing Your Human Being
Sometimes, despite your best training efforts, your human will stubbornly resist bending to your whim. In these extreme circumstances, you may have to punish your human. Obvious punishments, such as scratching furniture or eating household plants, are likely to backfire--the unsophisticated humans are likely to misinterpret the activities and then try to discipline YOU. Instead, we offer these subtle but nonetheless effective alternatives:

Use the cat box during an important formal dinner.

Stare impassively at your human while it is attempting a romantic interlude.

Stand over an important piece of electronic equipment and feign a hairball attack.

After your human has watched a particularly disturbing horror film, stand by the hall closet and then slowly back away, hissing and yowling.

While your human is sleeping, lie on its face.

4. Rewarding Your Human: Should Your Gift Still Be Alive?
The cat world is divided over the etiquette of presenting humans with the thoughtful gift of a recently disemboweled animal. Some believe that humans prefer these gifts already dead, while others maintain that humans enjoy a slowly expiring cricket or rodent just as much as we do, given their jumpy and playful movements in picking the creatures up after they've been presented.

After much consideration of the human psyche, we recommend that cold-blooded animals (large insects, frogs, lizards, garden snakes and the occasional earthworm) should be presented dead, while warm-blooded animals (birds, rodents, your neighbor's Pomeranian) are better still living. When you see the expression on your human's face, you'll know it's worth it.

5. How Long Should You Keep Your Human?
You are only obligated to your human for one of your lives. The other eight are up to you. We recommend mixing and matching, though in the end, most humans (at least the ones that are worth living with) are pretty much the same. But what do you expect? They're humans, after all. Opposable thumbs will only take you so far.
