The map you see in PETFON App is managed by third-party services , Mapbox and Google Map. We use their map services, but have no authority or ability to adjust their maps
You could try them both and see which map works better in your living area.

In very few areas, both map suppliers did not update in time, the map might be blurry or outdated, please go to Mapbox Map/Google Map Feedback page and tell them that the map in your living area need an improvement!
