Nest

You have no idea (this is me, Harry), how complicated it is to build a nest. 

You have to have architect designs, engineers, and all sorts of things!  So - here's me doing it all by myself.  I know!!  I must be a doggy genius of sorts.

I'll tell you my secret!  You dig and dig and dig, and scratch and scratch and scratch, and you create a sort of curved thingy for a roof.  Then you get your favourite toys and drag them inside.  Then you are so exhaustipated, you have to have a nap.
