So I understand lion meat is purposely rare and hard to get by BUT realistically if you're killing pride members for karma...there's a sack of meat laying around for you to take.

My offer is that if a full-grown lion is killed with 100% food and mood, there's a chance you can "harvest" their meat with an even lower chance of actually harvesting it. With people wanting to get the lion meat NCl, potato cubs and others will not be recycled into the game and some might have a chance to get a mute!
However on the same idea of having a lion full of in-game items, if you get the chance to harvest them, you could get a lion tuft/teeth/skull/claw instead! But also nothing because lets be honest? What can you do without opposable thumbs

I don't know how hard that would be to code but it would definitely be cool to get something from killing your pride.
The message would still be along the line of the original but with edits like:
" With the gruesome reasoning in your head, you approach the lioness, resting in the outskirts of your den. You attack her with brutal force, killing her on the spot and feeling her last breath wither away under your teeth. Before you leave, you realize you could harvest the lioness for some goodies. She can't even be free of you in death."
then have the option to try to get some items.
