It has been added yay!


Uterus Didelphys is when a female is born with two uterus instead of one, causing a higher chance of pregnancy, however the cost is that it can cause painful cramps and even painful intercourse which can be turned to not being able to hunt and every breeding causes her mood to drop 5-10%. Due to the nature of this mutation /disease miscarriages are more likely to occur than normal.

Positives:
+Higher Chance at Successful breedings
+Possibly having the ability to have 2-5 (Due to the second uterus)*
+Very Slight chance of mutation increasing(Though the chance for lethality can be higher with a lean towards conjoined twins)
+Nonlethal (However is the chance to have more than 4 cubs occurs the lethality can be possible due to a lioness not being built to handle birthing 5 cubs, or the fifth cub has a high chance of lethal mutation.)
Negatives:
-Unable to Hunt due to Pain enchanced by intense movement
-Mood drops during a breeding session
-Possible lethality if more than 4 cubs occur
Nuetral:
Slight chance of a natural miscarriage.
Slight increase in mutation with a lean towards lethality.
Rarity: 1 in 550 lions can have this disease for the reasoning stated below

Passable?: Yes with an increase of 1 in every 276 lions.

Visibility: If Visible, I believe it would show as an adolescent or just after the age of 2 as a visible bulge just around the loins, almost like she was entering her second trimester of pregnancy.

Picture: Okay this is a rough sketch I just made detailing the 'bulge' vs a normal lioness stomach.

Edit: Also the visible sign of it could be that the lioness in question has a larger waist or a more rounded belly.

Edit 10/20/2016: Just a brainstorm thought, instead of showing post adulthood what if while pregnant, the lioness is roughly a half size larger than normal, I will draw out the idea tomorrow and hopefully post.
