What did mom and dad mean when they said I was going to be a big sister? And what exactly is a Nutter Butter? Auntie says Nutter Butter is the name of the puppy I played with (well, I more tolerated him) a few days ago. Apparently, that puppy is now going to be living with us. Auntie says I have a few more days of just Old Man and I (and the cats, but we are not sure if they count). I will update you on what I think of my new brother once he moves in.
