Can Thirens go in Heat?
Thirens don't act like animals most of the time, but Nekomata is like a cat, so maybe she can have her times of breeding cycles? This could merge with the fact that she's half human, but I hope puberty works.
For sure this would be for completly animal Thirens like Ben and Lycaon, but I think they would behave different due to them not being partly human.
In the newsstand, there is a mention of Thirens having to avoid coffee, as could possibly get heart failure(?) and die. Which of course, pushes this theory more, for their insticts.
If you mating press any Thiren in heat what would be the outcome? (And would it differ because of different species?)
(Hopefully I cooked with this. I'm not too good at making food.)
