I found NI to be quite expensive for what it is, and I have doubts about the fat content, particularly as Henry must have a low fat diet due to Pancreatitis. Consequently, I have found it to be only a little more expensive to feed him with raw food from the supermarket. His main ingredient is chicken breast - £3.99 per kilo - from Lidl, Asda, and Aldi. Found in the frozen food section. This is supplemented with fresh liver and kidney. I also add a dessert spoonful of Hollins meat and bonemeal. A 4kg tub costs about £12 from Amazon and lasts ages.
