It has often been said that cats are natural sun worshippers, this is true in my house, even if there is only a tiny sunbeam shining through the window they will find it and sit in it.
The same can be said about the cats in this time-lapse video, we can easily see how they spend the day following the warmth of the sun as it passes across the room.
Could it be that cats are solar powered !!
If you liked that video then try this one!
