Bring a Friend

Another cat has been prowling around the house of late.
It sits outside on the table in front of the window a looks in. It's kinda like a stalker, but in a zoomorphic sense.
Mouser is on the inside looking out.
Yesterday it had a little catnap in the sun.
It looks like it's Mouser's furry friend. But I bet they get into a scrap now and then.
