another thing to try is if you go the chicken soup website they give a list of local retailers - then call around and see who has the 1.5lb sample bags they are only 2.99
hope this helps
i am doing that myself right now... altho i hate to say so far she isnt eating it i will give it some time
the sample bag is the perfect size that way if it doesnt work out you dont have a ton of food u spent a ton of money on
