Turns out, your cat can be a cheater

since a few days ago I've been trying to breed cats with seven or six stats with moderate success

however, these cats never cease to surprise me

First, put two male cats with nice stats on a room without mutation while I wait for a good female or unknown gender

Despite both of them not being gay or bi, even being brothers, they do the breeding and now are in love with each other

I learned my lesson and never did that again

then, on my main breeding room, I left two pair of cats that each had a cat they mutually loved

during the night, they get with the other one and make offspring, make the other two cats hate each other who then get into a fight that very night and ended up with one death

I'm not even mad, just genuinely baffled how it all just happened in one night
