Cat won't eat new prescription food

Prescription diets can cause cats to reject their food entirely or eat only a small fraction of their meals, leaving owners worried when the vet is closed for the weekend. This sudden refusal to eat stops cats from getting the nutrition they need and leaves owners feeling helpless without guidance.

My boy Loki is getting real picky with eating and it's starting to worry me. He is still slightly eating but not to the amount that I feel comfortable with.source ↗

When it is feeding time he fully wants to eat and follows me as I prepare and place his food. He'll eat maybe a quarter of it then have no interesting at all.source ↗

Of course this happens going into the weekend when my main vet is closed. I feel like this is food aversion or he doesn't like any of it.source ↗
