My vet recently put two (of our four) cats on a prescription diet. We're having trouble getting all of the cats to accept it, and it would be easier (now and in the future) if everyone ate off of their own bowls so that we could track food consumption easier.
Another wrinkle is that we're moving in 6 months and I'd like to not have to totally retrain them when we move.
My husband wondered if we could train each cat to their own colored tray? I'm willing to try that, but also open to other suggestions.
