Just wanted to give you an update. I tried a couple of things (paste, drops) to see if adding those to his current food would entice him to eat. Nothing worked. But he absolutely loves the Weruva steak frites and scarfs it down every time. He is now back to eating his original prescription food in the morning and the steak frites in the evening. Thanks so much for all your input.
I think what OP means is that when you’ve been immersed in rationality for a while then suddenly in a situation where you’re surrounded by religious people again, the things that are “normal” to them can be jarring to you. It’s quite an “emperor has no clothes” moment.
