Well - I'm not a fan of Petsmart either but I have taken Izzy in her little bag to places like Lowe's, Target, furniture stores, greenhouses, etc. I would not take her anywhere where there is food, etc. No one really even knows she is in her little bag unless someone really looks inside by the mesh door. People just think I am carrying a handbag, plus she is very quiet and sits nice in her carrrier until someone does notice and then she is all over that and wants them to pet her.

Or they figure out something is in the bad when they see this nutty lady talking to her handbag.
