My idea:
To allow the chance of finding stats after battling NPCs.

1. How would this work?:
Pretty simple. Every chance you defeat an NPC, you have a chance of gaining a stat (I think 25% chance is fair) depending on the NPC you defeat. Each animal gives out different stats. This is a tentitive suggestion, as I don't know how the admins will want to code NPCs as the game goes on.

2.But players could abuse this to get really high stats!
I would also suggest a cap on it of only 10 stats earned per day. This isn't to many, as your lionesses can currently earn 10 stats as of right now per day. A bar could read overhead as you exploring on how many stats you have gained. Even though it isn't much, you can battle specific NPCs to gain stats where you want them for you lion.

3.Which animals earn which skills?
Going off the chance off 25% for earning a stat after each battle, the stats that could be earned from the following enemies:
