Metacognition Unique to Us?

Would it be correct to say that metacognition (thinking about thinking) or the ability to observe one's thought process, emotions and behaviours is only unique to humans? (it seems animals and artificial intelligence can do most other cognitive processes). 

State of Being and Transitions

Being in a state does not guarantee staying in that state, control of state transition can be achieved through awareness and meta-cognitive practice.
For example you could be completely relaxed, but suddenly snap when your hot buttons are pressed. What can control you suddenly snapping is immediate awareness of what is happening and appropriate intervention before "amygdala hijack"
