What is the most common command you make to your cat?
If you are a dog owner, you may substitute. Ditto for parakeets (although I'm not sure that parakeets take commands very well. Joe? Tracy? Care to weigh in?)
If you have no pets, substitute children. Or whatever.
I rarely make commands of Sissy because she's generally well-behaved and not a nuisance in any way whatsoever. The same cannot be said of the Tot, so I have two most-common commands to offer up:
1. Get out of the way, boy!
2. Boy, get out of my shoes!
