This morning both of the cats were hollering at me until I got up at 05:30 am.   I got up and got them fed and then it was play time for them.  after about 10 minutes of playing their version of tag everything got real quiet. 
I guess they tuckered themselves out!  They can be so silly at times.  Sammy can be found in the same place every morning but you never know where you will find Shorty!
