Applaws,or not applaws

As Hanks got older he's become fussier. At the moment he's having three pouches of Iams Meat & Gravy, (hates the jelly version) with kibble constantly available for him.
As a kitten, we mainly gave him raw meat, prize choice with rabbit being his favourite. Unfortunately he went right off it and prefers the meats with gravy. I will probably try him again with a couple of different ones though again to see if I can get him back onto it. perhaps the tripe and rabbit again
