To Love a Cat

There is about 20 or so inches of snow outside. So I find myself sitting in my recliner with a movie, a key board and a thick warm blanket. And what would complete this portrait? Well besides a cup of hot chocolate, all you need is a fluffy cat.
What is it about a cat that feels so right? Why when I hear the gentle rumble of its motor do I get so happy?
But why? The love of a cat is so 'fickle'. Felines don't run at your beckoning call, at least most times. They are full of sass and will power that only a two year old can rival. And they will get up and leave whether you want them to or not.
They make me happy that's all I know. And maybe that's all I'll ever know. And I suppose that I'll have to be okay with that.
