Year ago: I hadn't done the supper dishes yet and there was a frying pan on the stove with bacon grease in it. I'm on the far side of the living room and see my cat on the stove lapping up the bacon grease as fast as he can. I yell and him and start across the room to grab him.
He looks at me and I can just see the wheels turning in his head, "OK, let's see, shall I jump down now and get under the couch so I won't get in trouble or shall I see how much more I can lap up before she gets here. It's really tasty and it's almost worth it to get in a few more licks before she gets here....."
He chose to keep lapping. I grab him by the scruff and start scolding him. The whole time I'm yelling at him, he's licking his chops and yowling, "NYOM, NYOM, NYOM, NYOM...." which translates to, "Ummm, good, there's some more grease on my whiskers to lick off and it was really, really worth it!"
The difference between dogs and cats. The dog misbehaves, you yell at him, and he's very sorry. He's ashamed. He knows he's lower than a snake's belly and he begs for your forgiveness. He'll do it again, but he'll be just as regretful next time. A cat, on the other hand, isn't sorry, isn't ashamed, isn't regretful. He's going to do it again. He knows that you know he's going to do it again and that he isn't going to be any more sorry next time, so "WHY THE HECK ARE YOU MAKING SUCH A FUSS ABOUT IT, LADY???? JUST GET OVER IT AND WE'LL BOTH GO BACK TO OUR BUSINESS!" as he stomps off oozing distain.
