So I and several others happened to notice that the lethal mutation deaf is a mutation that has a chance of your lion dying the next rollover between the ages 4 months and 4 years. All the mutation is is that your lion cannot hear. A lion like that obviously could not survive in the wild on its own without help. How about a role similar to broodmother where you can assign a lion to your Deaf lion and give them a higher survival chance. Maybe not a 100% chance but at least as they bond together they could. This won’t change their ability to hunt or normal stuff they can’t do.

It think this feature would be good for people who wants their deaf lion to live longer than it should or a normal life like your average lion. These can have small little new interactions you can get when you visit your lion with both of the lions bonding. Maybe this could be for blind lions, because let’s be honest it doesn’t make sense how a blind lion can survive longer than a dead lion. A deaf lion is more vulnerable just like Deaf lions are. I just didn’t see this making sense. The same goes for eyeless lions.
