Nas greeted me again today.  By the time I grabbed your mail and walked around to get his food bowl, he was sitting staring at the back door like he wanted to go inside.  Either that or he is really vain and could see his reflection in the glass.  I gave him some soft food this morning along with a little bit of the dry.  I also cleaned up a furball on the steps so it wouldn't petrify :)  Gotta love pet sitting!!  LOL
