We can't imagine Naruto without those six iconic lines on his face. A few animation errors in the anime forgot to include them and Naruto just doesn't seem like Naruto. What is the history behind those whiskers?

Kishimoto never explained the origin of the whiskers but there are non confirmed speculations of the whiskers.

The most common speculation is that Kushina was a pregnant Jinchūriki, so Naruto may of gotten some of Kurama's features(I was thinking of a word better than features but could not find the word I was looking for).

I don't really know if there was a confirmed reason for the whiskers on Naruto's face.
