Some kibble addict kitties can be quite the challenge, that's for sure!
Sprinkling his kibble on top of the canned is a great idea. Pile the canned food up in a pile then gently press some kibble slightly into the canned so that only half the kibble is sticking out, then some pulverized kibble on top of that. Another thing I have found is the hungrier they are, the more apt they are at eating something different. No different than children
, so patience and perseverance may be key to a successful transition.
Good luck!
