I used to have a lvl 215 Terror bird with an awesome melee mutation. But one day when I came back from gathering I saw that my fence that I kept my creatures in was destroyed. I thought "Oh Crap" and saw that a terror bird had killed all of my tames, including my lvl 215 terror bird. The moral is that Terror birds are cannibals and never keep your tames on passive.
