When Poof is nursing their first litter, he'll probably have at least one extra. Then a child of a family friend will fall for one of these adopted familiars and they'll be the parents of the first demon/familiar hybrids with no wizard added.

I was wondering how Arath would take it. Is he jealous of the little strays or will he treat them like his own? What about when finding a stray interrupts their date and keeps the sexy time (when Poof is old enough for such things) from happening.

I got it: Arath has Poof alone in the park under a star-filled sky, leaning down for their first kiss, when a small meow distracts Poof... (but I might be crueler than you are)

Poof's parents are going to end up with a huge family. And I don't think Poof cares what Academia thinks. If they really cared, they should be solving the problems that cause strays.

I'm kind of worried about the place No-el came from. There might be more kittens in need of rescue. I wonder if Arath would help.
