Okay, so lions typically leave markers and scents when in heat or ready to breed. In my previous topic, I talking about Admiring lionesses, but in all honesty, I think this idea sounds even better!
Maybe when exploring, you can leave scent marks, or sniff some out? Maybe Female lionesses in heat have a 10-20% greater chance of wooing them easier, making getting your first cub(s) in the clan easier to get!
I mean, I think this would tie in nicely, since every now and then you'll get a message while exploring that says "You smell your favorite scent... A lioness in heat! But she's too far away!" Maybe there could be an option to track down the scent, and find the lioness in heat and proceed to the Claim a lioness screen, in which the previously mentioned chance raise goes into effect! (\oUo/)
