I would have to say an emphatic YES to this question! LOL!!!

For example.....

Lilly once "snuck" a box turtle into the house! LOL!!!

My Butter sneaks up on us, if that counts! And there are always unsolved mysteries where he is concerned, like "how'd that light turn on by itself? Or How did the radio come on by itself?". That is one mystery that was solved. He also is an expert at shredding paper of all sorts, but usually does it when I'm not looking. And hiding? He is so smart! He now knows the order in which things happen, so he is incredibly sneaky about getting just far enough away from me that there is no way I can reach him! What a boy he is!
