Read the guide on how far cat food https://pacoandpepper.com/blogs/news/how-far-away-should-cat-food-be-from-the-litter-box should be from the litter box after my cat started going off her food. A friend suggested placement might be an issue and this article confirmed it. Covers the behavioral and instinctual background clearly and gives realistic guidance for different living space sizes. Helpful framing for a problem I hadn't considered spatial. Good practical cat care content. Made a change to the setup and her appetite returned to normal within a few days.
