The rules of the Death Note state that "the human whose name is written in this note shall die". There may (or may not) be additional rules which explicitly state that one may not (or may) kill animals with the Note, but based on the wording of this rule alone, it would be prudent to assume that the Death Note may not be used to kill animals other than humans.
