Cats do not enter this world unprepared. To wit:

• Retractable Claws
• Sharp Teeth
• Amazing jumping ability
• Purring
• The Plaintive Look (Meow optional)
• Style
• Grace
• Cuteness (this applies to kittens especially)

. . . and of course, the instinct to use all these weapons for world domination. You'd think that, armed with this knowlege, I would know better than to house cats in my domicile.

You'd think.
