Another idea for grazer vs gobler problem is to get a sensor automated bowls, there are few on the market. I'm not sure if I can recommend the ones I have (certainly not for every cat), but they do awesome job keeping the food freshly sealed. And the sensor can be manually turned off so that the gobbler won't get to the food, I just need to be ready to open it when my grazer is ready to eat. Ideally microchip operated bowl would be the best, but they're too expensive imo. For the below I paid $30 and I don't think I'd pay more for this model.
