Work Text:
Castiel and Balthazar live in ground floor apartments facing each other across an alleyway. They both have indoor/outdoor cats that leave in the morning and come home at night.
Their cats seem to be item.
Every day they greet each other in the alley, nuzzling, tails brushing, and wander off together. They’re still joined at the hip when they return, and the neighbours often report walking by them snuggled up somewhere.
And every day Castiel and Balthazar’s eyes meet across the alleyway; they give each other knowing winks and smiles and pretend their only interest in each other is through their cats.
Late one night, there’s a knock at Balthazar’s door. A quick peek says it’s Castiel, cat in his arms.
Is this it? Balthazar wonders. Has he come on the pretext of letting the cats play, so Balthazar can invite him in for a drink “while we wait,” and they can finally get to know each other?
Except when he opens the door, Castiel doesn’t look happy.
“Excuse me,” he says haughtily. “I was unaware your cat wasn’t neutered.”
“…Heh?”
Castiel's cat is pregnant.
“W-what’s that look for?!” Balthazar stammers. “I didn’t know your cat wasn’t spayed!”
Castiel doesn’t flinch.
At least Balthazar still gets to invite him in?
