Hello guys! So I have a new Lethal mutation! So I'm thinking in the art the cub will have its mouth open with no teeth inside. My thoughts where that it would die at 5 Months. My reason for this is in the first 5 months, it can still nurse from its mother, but when it's time to eat meat the cub cannot chew so it will starve to death or choke. Any suggestions feel free to comment bellow.

1) Is it a real mutation?
Yes it is
2) What is it called?
Edentulism
3) Is it documented in animals, particularly large cats or other carnivores?
I know in smaller felines it's possible. Tbh, in big cats I'm not 100%. Not a lot of people are interested in this topic, but I'll continue my research until I get a "No" or a "Yes"

Possible Death Months:
3 months
4 months
5 months
6 Months
7 Months

Message Idea:
Your lioness (name of lioness) has given birth to (number of cubs)! One cub seems a bit odd, and as you look closer you see it has no teeth.

Death Message:
You found the body of (name of toothless cub) laying in the grass. As you look closer it seems it has starved to death.

Art Idea:
Maybe the cub is laying on it's side, and it's sides are 'heaving', it's mouth is open and there is just a gap (like with human babies before they get teeth) in it's gums?
