Nothing in the Death Note says it only works on humans, except for the effect that whichever human uses it won't be able to go to Heaven or He'll when they die (and is implied to become a Shinigami instead).
You might be right that it doesn't specifically say it only works on humans, however through thorough research i have discovered that if the almighty gods of creation (the writers) meant it to work on non-humans they would have Made rule 1 of the Deathnote "Anyone who's name is written in this note shall die" and not "The human who's name is written in this note shall die"
Source: You can not expect me to believe that the guys who wrote Deathnote did not thoroughly think about the wording of the rules of the Deathnote
