This happened on my first single player server, before level ten. Take note I had no idea how to tame yet, so this was very new to me.

I stayed on a beach that was nearly completely safe, no theris or raptors. The only thing that made it hard to survive was…sarcos. There was a sarco living right next to were I set up my mini camp (not a base) and it kept attacking me. But once I was walking around, and found it with no stamina. I knocked it out, and put in a bunch of food. It’s taking was about halfway when I realised that it was about to wake up, so I searched up a bunch of videos. They all said “put narcoberries in it” so I did, but non of the videos said to press feed. So it woke up and I never got to tame it.
