Japanese cats seem to become immune to cat-deterring spikes (neko-yoke no togetoge in Japanese), which anyone could buy at every 100-yen shop (similar to dollar stores) to prevent cat fur from appearing in undesired places like kitchen table, air conditioners, fences etc.
These photos show that cats were able to adapt to these severe measures and no longer pay attention to the spikes – if they want to be there, they will go there, spikes or no spikes.
Australian government organization came up with a project to show people how their pet cats are actually active. They used GPS trackers to map out their activity. In Australia cats are considered invasive species and can have devastating effects on the native wildlife. Often cats' owners are convinced that their pets don't roam around at night, so the aim of this project is to show them what's really going on.
