The new sensitive stomach and alergy one is pretty decent. I think its the only formula from purina without corn or bi-products, but dont quote me on it.
I did however just but some food that I cannot find around me at
www.petfooddirect.com The food was about 6.00 cheaper than what I currently get, and only 10.00 for shipping, so no all that bad.
Its good for those who have no other outlets to get some good stuff.
