Toto did that more when she was much younger! It IS funny ... we called her the "Queen" because she would sit up on Patrick's shoulder when he was sitting on the sofa! She would sometimes just curl up and sleep! She doesn't do it as much now since she discovered his chest! Now ... THAT"S her favorite spot in the whole world ... whether she is sleeping or just sitting up there "surveying her kingdom" ... she just loves it there!
I think it makes her feel safe, I know it used to make me feel safe to lay my head on his chest! NOW ... I couldn't tell you how it feels ... since the furball took my spot!!!
