Okay if there happens to be a topic about this I am sorry, I looked through and didn't see one myself.

So females have fertility which determines a whole lot of things and can give you mutations, but what about males? It would work just about the same way the female would and when you bred it would have the same sort of "effects". So if you have a goddess of a lioness, and a very low male, the female might not get pregnant. If they are both very low (say under 30%) they would have a really low chance of having cubs, but if they did have a cub or two it would have higher chances of carrying a mutation.

Now some will being up "but there will be too many mutants jaybear, that wouldn't be good." Yes and no, there would be slightly higher chance to get those adorable muties we love, but at the same time is increasing the chance the mating will fail.

But how is this a good thing? It's a bit more realistic, since males also carry fertility issues. It will raise player's chances of a mutie (only by some), and decrease the cub craze which fills and fills the lion population. Cubs are born everyday and players don't want to chase since they have to wait a whole 20 days for their lioness to go back into heat. Lioden gets stuck with endless cubs.

Some might not like this, I know, but I feel like it would put more pressure on having fertility. I have not yet had a lioness with very low fertility fail a breeding; it would make studs better as well. People who breed for muties might want a very low stud, or if you just want some cubs a "God" fertility might be worth more. And there will always be the same craze over looks and stats, that doesn't change much.

Add on edit- possibly their fertility determines how much energy is consumed for a breeding?
90-100%fertility- normal energy consumption
70-89- subtract 5 energy
40-69- subtract 10 energy
Below 40- subtract 15
