Pets are little pieces of our families. My dog specifically, is like a toddler who never gets older and she's always very aware when she's done something wrong.

Maybe your pets are the same. Do they have a safety spot that they run to?  Do they just give you that "I'm so sorry" look. Penny does that, too, but mainly she runs to a very specific spot in the house thinking we're playing a game of hide-n-seek and she's found "safety" so she can't get caught.
