Hello! Much like fertility being shown, there should be a mutation Percentage shown on a lioness or lion, where it shows the chance of some kind of mutation being passed on a litter per cub, because the wording of many items make it seem like there is a hidden percentage, so I think it should be a number that is visible on game, or you can pay similar to the fertility to get the % revealed, where certain items can either have a 1 time use permanent increase, or hard to get items can have a low permanent or temporary mutation percentage increase, where using infertility, lion meat, lion scrotums, GMO cows, CRB, ect... would show a boosted number, again in the same fashion that fertility and chasteberries work, and it could include where if two high mutation percentage parents have a litter together then the cubs could have a slightly above average percentage, it would encourage people to not be so against a multi lineage stud, as having a long generation could encourage a chance at more mutations to a certain percentage.

As well there should be slots or an area where it shows what breeding items are stackable and which aren't, so that way new players and those not heavy into mutation breeding don't accidentally waste breeding items that don't stack (ie. Lion meat, and GMO cow) there could be a slot that once used it will "fill" it, so then another item that would take that slot wouldn't get used as well it would show what items can be used each breeding so again it helps players know if they are using everything needed/wanted in that breeding, its definitely an improvement having a banner pop up with items used on mom and dad, but would be nice to have a little section where you can directly eqip what you want onto each lion on their page, vs your hoard and having to find the item plus the right lion

If you don't support this idea or have feedback please leave a comment! I would love to get some more opinons on any/all of my topics! 😁
