cat is sick after eating Innova

Was it from the same can or a different can the second time - the yellowish bile seems like it might indicate stomach trouble.  My cats have done this before, but usually it is just a one off.  I don't have any cans of Innova at the moment, but I think it is chicken based.  

It was from the same can, he ate half of 5.5oz. Before that he was eating a lot of different brands of food mainly chiken, turkey, fish and vension and never threw up after even when he didn't like it much. He was poisoned by menu foods a while ago and thats when he was throwing up a lot.  Would they test the food if I send it back to Natura Pet Products?

I hope he's feeling better by now.  But, just curious, has he always eaten foods with veggies?  I know sometimes that can really upset them. 

He looks like he's feeling better( going to return Innova for a refund), he ate some Avoderm this morning.  I don't see anything in the ingredient list of Innova that I know would upset his stomach (here is the ingredient list: http://www.innovapet.com/products/default.asp?id=34), he's used to eating grains and vegetables from the junk food I used to feed him before I knew there was better food.  He did get sick from tainted food when Menu foods were being recalled.  It just surprized me how all of a sudden he felt so sick from a suposedly good food like Innova. Hmm, the symptoms were similar to eating tainted food.
