An aquarium is just interactive television for cats. Anything on the ground is a cat toy. Anything not there yet, will be. At least dogs do what you tell them to do. Cats take a message and get back to you. Buy a dog a toy and it will play with it for ever. Buy a cat a present and it will play with the wrapper for 10 minutes. Cat's motto: No matter what you've done wrong, always try to make it look like the dog did it. Cat rule #2: Bite the hand that won't feed you fast enough. Cats are rather delicate creatures and they are subject to a good many ailments, but I never heard of one who suffered from insomnia. Cats are smarter than dogs. You can't get eight cats to pull a sled through snow. Cats aren't clean, they're just covered with cat spit. Cats don't hunt seals. They would if they knew what they were and where to find them. But they don't, so that's all right. Cats instinctively know the exact moment their owners will wake up. Then they wake them 10 minutes sooner. Cats know what we feel. They don't care, but they know.

I had to get rid of my wife. The cat was allergic!"
