Ok I hope this isn't freaky lmao!!
New item idea: Lion's Womb. Or uterus, whichever you prefer
AKA: Lioness Womb, Feline Womb, I'm not sure what sounds best

Here's a mock-up I drew!
I just looked at a basic anatomical drawing of a felines' uterine system


How would you obtain one of these items?
Well, I'd imagine it would have an already extremely rare drop rate... And to gamble for that chance, you would have to kill lionesses in explore, or in your pride.

? - There could be a bonus OR a penalty in drop rate for killing pregnant Lionesses.
? - for the above, if your karma is good, it could lower the drop rate, if it's bad it might slightly increase the chance, but not by much.
Suggestions are welcome

Now to what this item would do...
Quick Interjecting Edit
((I wasn't too familiar with the double uterus mutation, my original idea does seem to mimic it - see the NEW IDEAS section below instead; I'll still leave my original but conflicting text with strikes though!))

Since felines irl can have multiple offspring from multiple fathers... ideally, this item would help with a lioness with something like that.
The organ would be fed to a lioness, and in turn allow her to breed with multiple males in one heat cycle. Up to three? (So 1 male a day/RO)
It would NOT increase fertility.

50/50 chance at rejecting any male on her 3rd day of heat if already successfully bred to two males before??

Each cub may resemble a different father, or there's a tiny chance to mix the multiple males' genes together.
The first scenario would allow her to have a max of 3 cubs in a litter - 1 cub a day, per breeding male. The same male cannot successfully breed more than once.
Since this item could basically guarantee a litter of 3, that would contribute to its rarity.
This would also definitely increase studding and trade opportunities!

This is just the first idea/premise I thought up, so as I said before, suggestions are highly welcome! <3

Is this something you would be interested in? ^^

---------------------------

NEW IDEAS:

--Allows multiple males to be bred to the fed lioness in one heat. (2-3 max still?) Instead of producing multiple cubs, the litter would instead have a chance to pull from a pool of genes/markings provided by the different fathers (and lioness of course)
