When you have poor social skills but try to make friends anyway. This cockatoo just wants to fit into the cool cat crew that he's living with! Not only does the cockatoo meow at the cats, when one cat got too close, you can also hear the bird hiss at it. True feline language has been mastered by this smart birdie! If those cats were confused as to why this other weird-looking "cat" was meowing at them, that hiss would've solidified him being one of them.
Good job, Sir Cockatoo, we are thoroughly impressed by your dedication to infiltrate the feline crew.
