So I had this idea that when lions participate in close inbreeding, like if a lion and their child would breed to each other there would be higher risk of their cubs to get ether a leathal mutation or a disability like deafness or blindness. I also thought that we could include missing limbs, so intread of 4 legs they would have a random chance of only having 2 or 3 legs.
I also thought that would be an interesting addition to the breeding part and a way to involve herritage.
Since a wild lion would be unlikly to survive for long with this kind of mutation it would be a leathal. Maybe they die randomly from 5-12 months?

UNLESS, and this is just a fun event thing I thought of!
On the poacher event in March you could have a verry rare incounter with a group of humans/vets that are trying to prevent the poachers, they notice that one cub in the pride is missing a leg and you gain an item, a prosthetic. You can then use that item on said lion (this would only be a decoration and would not have any function other then looks)

Yeah so that's just something I thought would be a nice addition to the game!
Please if you don't support tell me why :)
