Our upstairs cat is beginning to lobby for us to abandon the downstairs cat. “That damned cat has outstayed her welcome anyway!” Upstairs kitty doesn’t care that downstairs kitty was living here for years before upstairs kitty ever showed up.
This is the way it is with cats. Diplomacy is for dogs, those stupid, drooling beasts.
We’ve had to deploy peacekeepers in the neutral zones to fend off skirmishes, but it’s hard to be vigilant 24/7. We can’t post a child on the front and back stairs every minute of the day to prevent an escalation of tensions. Instead, we rely on long stretches of daytime catnaps and general feline boredom to prevent comingling. Sometimes downstairs kitty will make a secret foray into enemy territory to eat the leftovers or get a scratch behind the ears from family members. The incursion usually leads to screeches and drawn weapons.
As of this moment it’s all quiet on the western front.
