Maisey has been on the Chicken and Green Pea formula ever since it was suggested to me here for my cat's sensitive tummy. It has done wonders for her. I'm not sure how much is sensitivity and how much is food allergy, but she rarely vomits and is doing great. However, I have a concern with it lately b/c I read a review on Amazon saying that a new company packages its food for them now, and the formula has changed. Her cats have trouble with it. She has said Consumer Reports and others have been reporting problems. Anyone know anything about this? I notice the price has gone up, and the store that used to carry it in town went OOB and was replaced by Petco which doesn't carry the Chicken formula. I'm not out of food yet, but, in looking ahead, should I stick with LID, or are there other foods that work well for cats w/food allergies? I've tried Pro Plan in the past, and have done several sensitive tummy foods, but I think it's an issue of allergies. She was dxed with a food allergy, is susceptible to other allergies as well. Other problems were ruled out. Like I said, she's doing great and hate to mess with a good thing. But, if there are new issues with this food and the availability is decreasing, maybe it's time for a change.
