The owners say they never trained Bosia to say the word and were shocked when he came out with it one day.

However, he then started to repeat the word "mama", according to Natalia.
She claims he now says it daily, and she believes he knows exactly what the word means.
Natalia continued: "It seems that he likes saying mama.
"We did not train him on purpose. It all happened by itself."
