Captured bear cubs will not convert in the animal pen. I had two bear cubs and a wolf pup that I threw in a regular animal pen. One bear cub and the wolf pup both got timers while the second bear cub didn’t. Both the wolf and the single bear cub converted, while the other bear cub was still unaffected. I removed it and placed it back in to the pen, and still no timer. I caught more bear cubs, still no timers… All other animals seem to be working, just not bear cubs.
Yes. I’ve tried both uncooked human and feral meat, which both worked in the past. I’ve also tried removing them and re-adding them after a few minutes and even capturing new bear cubs. It’s really weird, as it only this issue only affects, specifically, bear cubs.
They don’t eat either of these foods. Try with berries, honey or raw fish, with honey having the highest chance for greater pet (resp. Shadespiced Honey). For the full list, see here: https://conanexiles.gamepedia.com/Bear_Cub_(Pet)
