Breeding

In one of Tiy's friday updates you said every npc will be different, and breeding could play into that, like say color, or size. If breeding is implemented, I would like to know if it would be say xs + xu = xt (only pets from the same main branch wolves or instance, could breed) or would it be anything can breed?

 

Is this a question to the devs or a 'i wonder' one?

 

I asked Tiy about this stuff, and I thought I should post this on the forums.
