I noticed ever since starting the raw meal once a day with Kananga, he doesn't need food right before bedtime anymore. Before he'd need some kibble so his stomach wasn't empty overnight. I tried forgoing that to see how he reacts with the new food and he can go 12 hours without a meal just fine now.
I should also note that as quiet as he is, his raw meal (@ dinner time) more than often gets him so excited that he lets out some interesting noises (not a full yodel quite yet, but the attempt). I thought that was interesting as he's not very food motivated. He'll do anything for his raw meal though.
