Why catnip of course. The only thing keeping us safe is they havn't figured out to use the childproof lighters... yet We have BAD cats.
Bad Cat? That's gotta be an oxymoron.
What would a bad cat do? Bark? Not bury its poop? Run around the neighborhood no matter how much Master yells? Wait, no, cats do that last thing anyway.
I think our cat is pretty much a model of decorum. She doesn't shred things, unless they're HER things out in the garage (I think she figures anything out there is hers, and so fair game); she's never tried to jump on my desk (she'd collapse the keyboard drawer if she tried to sit on my keyboard!); The only "bad cat" antics we've seen is if we open the front door, not expecting her to be lying in wait behind it, and she runs out like a black streak of lightening. But she's a sucker for a white paper plate, knowing that they usually contain Tuxie Treats.
One thing she does, I didn't even know about, till my husband told me. She was always a garage kitty, going outdoors in the daytime. When fall came, with cold rain, she graduated to being a house kitty, but still slept in the garage at night. When it got REALLY cold, she graduated to sleeping in my husband's room at night. He told me that recently, she's started getting up on his pillow, and batting at his head while he's sleeping -- revenge, no doubt, for all the pats and rubs we inflict on her when sh's sleeping on the back of the couch.

And the other morning, when his alarm went off... the cat was sitting there on the nightstand, right in the way of the alarm clock, going "meow?" and batting at his hand as he reached for the snooze button.
