Hot Topic Domo plush backpack may contain cancer causing chemicals?

Ok.... So yeah, I was interested in buying until i saw that.... Obviously I'm not gonna chew or bite it, but what if I accidentally inhale it or something? It has a warning on stuff about the state of california identifying the chemicals as cancer causing, should I really be worried? What about inhaling accidentally? Cuz like whenever you lie your head down on your backpack because you're tired, you breath next to it, is that something that could you know....cause cancer? Idk, I'm kinda concerned.
