The holy grail of cat beds

This is a very important spot in my house. Almost 24/7 it is occupied by a cat (I have three). Most often it is Trouble (pictured here) or Hollie. Heaven forbid one tries to get up there when it is occupied though. Tilly and Trouble will share and get on but Hollie is the outsider! She gets her pay back though as she won't let them force her off and she can sleep for hours ;).
