Starting off with the basics:

~mutations can occur from any lioness, of any fertility, although the lower the fertilities have a slightly higher chance

~Breeding any mutated lioness' without items will give you the same mutation chance as breeding a non mutated lioness (The exception to this rule are Leopons and Overgrown fur, these are the only two 'Passable' mutations)

~Unless it is Piebald or Primal, breeding to a mutated male to get a mutation is pointless, it does not pass, end of story sorry

~Each cub in a litter rolls their chance for mutation separately, just because one is mutated doesn't mean the others had increased chances also


Mutation Items (from lowest success rate to highest):

~Cotton Root Bark This increases your chances to higher than a 1% fertility lioness, but also increases the chance of a lethal mutation (if anyone has average success rate % let me know :) )

~ Lion Meat This item gives much higher chances of breeding a mutation than a 1% lioness would, but not as high as a GMO cow would give (once again if anyone has average success rate % let me know :) )

~Lion Scrotum This item works only on mutated lioness (excluding Leopon and Overgrown fur, since as mentioned earlier these can pass naturally) It gives a 25% pass rate per cub in the litter

~GMO Cow This gives your lioness cubs a high chance of being mutated, it's estimated at approx 50% but no confirmed percentage

~Mutie on demand: Overgrown Fur/ Piebald/ Primal Since they're technically a mutation item XD and has a 100% success rate!


Now it gets complicated: Stacked Items

I'm going to explain this by saying there are three different 'Slots' used when breeding, One and Three taking items, and Two being the natural mutation chance

~Cotton Root Bark can be used alongside any other mutation items, lets say this takes up Slot One

~The lioness natural chances of throwing a mutation takes up Slot Two

~And last but not least Lion meat, GMO Cows, and Lion Scrotes take up Slot 3, this means only one can be used per breeding, and those three items do not work with each other

~Each of these items chances roll separately and in that order,
e.g. With a Dwarf lioness using a CRB and Lion Scrotum
Cub 1: Cotton Root bark activates, cub has Folded Ears
Cub 2: CRB fail, natural mutation chance activated, cub has Adult mutation
Cub 3: CRB fail, Natural mutation fail, Lion Scrotum activates, cub is a dwarf
Cub 4: CRB fail, Natural mutation fail, Lion Scrote fail, cub is non-mutated



Extra note for those using Primal studs while breeding Leopons~ the Primal mutation will roll first and then the Leopon, so while it's incredibly unlikely that the primal mute would overwrite a leo cub it's still possible
