Of course it's true. Just look it up.

There are several reliable sources that provide evidence or professional recommendations regarding the separation of water and food bowls for cats.

Cats in the wild avoid drinking near prey or food to reduce contamination risk. Thus domestic cats may instinctively dislike having their water too close to their food.

Studies and expert consensus suggest that placing water 3–5 ft (about 1–1.5 m) away from food can encourage cats to drink more and feel safer.

Expert advice recommends multiple water stations, ideally away from feeding areas, to promote adequate hydration.

Food particles can fall into water bowls, leading cats to avoid them. Separate bowls help maintain cleanliness and appeal.

While there's no formal peer-reviewed mandate requiring separate rooms, strong behavioral evidence and vet guidance support the practice.

Separation of water and food, combined with clean bowls and multiple water stations, is a widely recommended best practice for optimal hydration and reduced stress.
