Yes Mother

Uru and Scar dont get along very well, and whenever she talks to him its always something idiotic or just yelling. 

in my theory Scar is not the son of Uru and Ahadi, he was taken in after a big war between Pridelands and another pride. Ahadi has no problem with him as he himself was a rough before he became the Queens mate, but Uru never bonded with him nor saw him as her son. Yes she fed him and did all a mother would do, but she did it out of duty not out of love.
