How I can tell that Corky is the youngest:
When I get home, he’s usually the first in line to greet me at the door. Typically at a quick trot, and a bit of bark. His usual nappy spot is probably on the bed, or under my desk.
Willow’s become smart enough to not get off the couch unless she sees something, or hears something more distinct than the neighbors. Like seeing me walk into the room before trotting over.
Misty is usually cozy on the bed, and will usually whine while dancing up and down the edge of the bed. Because she knows that I’ll sit on the bed to take my boots off.
