Can someone help me out with a list of alien non-sentient species? Player wanted to play a genetically modified animal (ala Rocket Raccoon) After memorizing so much stuff to the regular alien speices, i have no room in head left for regular animal names as well. Anybody able to help me out here?

If you search for the term “nonsentient” in Wookieepedia, you should find a large number of articles turn up. Most of those should be relevant to your question.

For example, try this URL: http://starwars.wikia.com/wiki/Special:Search?query=Nonsentient
