Where does one end and the other begin?

Mia and Ethel are snuggled together on the heating blanket. It's hard to tell where one ends and the other begins............
Ethel is 15, and blind and Mia is 17 and a bit irritating. She has started to wake me up around 2 am to slip under my comforter and cry. I have to put the iPad on YouTube and play a squirrel video to shut her up. As I write this she is watching waiting for her turn to watch squirrels in the park.
Be jealous this is my life.
So
G'Day down under and good night to the north!
