IAMS Advanced Nutrition Kitten with Fresh Chicken

Purchased the 10kg bags to save money but both of my kittens ended up being sick and having diarrhea, still have one bag unopened and no use for it, a very unhappy regular customer

Having purchased this previously in smaller sizes for my kittens I thought I'd try to save money and buy the bigger bags but both of my kittens started being sick with diarrhea, such a shame as I have one 10kg bag left and a container full of emptied bag. A very unhappy regular customer

I thought this was a good brand, but my kittens refuse to eat it... I don’t understand the reviews.
