I smell a cat

Last night TJ and Pat left and did not come back.  I had to sleep by myself in the kitchen.  I never know if they are going to leave for a day or a month or many months.  This time they were just gone one night.  When they got home I smelled a cat.  They spent the night at Pat's parents house with the cats.  They came home to play with me.  They like to play their Nintendo game and I watch them.
