Mutations are one of the most popular things on Lioden and makes it stand out from other sites like this, but I think disabilities would be something fun to add on some more challenge!

Warning, some images may be disturbing.

Physical disabilities such as the following;
"Broken" tail (half limp or kinked) : kinked

A broken spine and/or legs (lower) : spinal
(hind legs would be dragged if spinal)

A twisted hind leg / fore leg : leg

Missing / torn off ears : ears

I don't expect them to be added straight away if the ideas are liked, more of a slowly introduced thing?

How you'd get them :
rare random "encounters" as cubs will give your lion the disability.
For example, like the cub accident warning would have a very low chance of producing a disabled cub;

This is one of the current encounters,

In trying to investigate that dark, shadowy area, 105 Diabolical 6m accidentally ran into migrating buffalo! It was found by a lioness during a hunting run and brought back bruised, bloodied, but otherwise alive to your den.

But in a rare case, you'd be notified that your cub was either found or dragged itself back with said injuries but now with one of the listed disabilities; in this case probably a broken leg!

I don't think they should be as rare as mutations, but something that can be collected and sold like them! (Depending on the disability, the lioness/lion may not be able to patrol or hunt or be kinged) and they won't pass like mutations, so it'd be *pure* chance that you get them! No cotton root bark for breaking your sons legs!

If you don't support, explain why please! :)

EDIT: Due to me not considering the factor of expensive heirs, some good ideas to prevent / remove the disabilities would be;
1. A 1-2 GB item from oasis that removes the disability
2. When 100% protected or protected by a broodmother there is no chance of getting this disability, and when over 60% trained as an adolescent

EDIT2: Removed adolescents as it didn't make much sense
