They learned that if the frame is in place, they can't walk through the nothingness (which used to be glass but now actually is nothingness). | |

| Apr 11, 2019 at 9:05 | comment | added | Ruadhan | Well that's puzzling terminology :P As far as I can tell, the cattle-grid isn't a canadian invention and isn't unique or even particularly prevalent in canada. The patent came from Nevada of all places. Strange to emphasise canada so much on the wikipedia article | |

| Apr 11, 2019 at 8:53 | comment | added | Nyakouai | @Xen2050 Midly insulting? On what account? It's the name we have here. English have "French fries", never found anyone who thought it was insulting? I'm confused here. Plus I specified in the edit that the english name is a cattle grid. | |
| Apr 11, 2019 at 8:50 | comment | added | Xen2050 | Neither google nor I (in Canada) have ever heard of a cattle grid/grate/guard being called a "Canadian bridge" before, but it does sound mildly insulting. Maybe you should change it & use a common term everyone & google knows | |

| Apr 10, 2019 at 16:47 | comment | added | Nyakouai | @Ruadhan Just looked at the wikipedia entries, and I'm thoroughly confused. Entry in my language say it's about the void. Entry in english say it's about the bars and cattle not being able to cross... Is my whole country deluded or is there differents reasons? The plot thickens... | |
| Apr 10, 2019 at 16:41 | comment | added | Random832 | @Ruadhan there are painted cattle grids. Cows are smart enough to know they'll fall into a real cattle grid, but not that they won't fall into a fake one. | |
| Apr 10, 2019 at 14:28 | comment | added | Nyakouai | @Ruadhan Thanks for pointing that out. If I remember, I'll look into it later and edit accordingly. | |
| Apr 10, 2019 at 14:27 | comment | added | Ruadhan | We have a fair few around my family's farm, cars can traverse a grid separated as far as several inches without issue. Cows definitely could step in the gaps. If it was just the void that was the methodology, the grid would probably be more of a mesh than a series of metal bars with wide gaps that risk injury if an animal actually stepped on them. | |
| Apr 10, 2019 at 14:24 | comment | added | Nyakouai | @Ruadhan Since cars use them, the few I saw during theoric driving lessons were tightly-knitten, and a cow couldn't have slept in the holes. From what I've been told, it's the sight of the void that keeps them from crossing. Could be wrong, it's not a first-hand experience. | |
| Apr 10, 2019 at 14:22 | comment | added | Ruadhan | I was under the impression that a Cattle-grid works because the cow's feet tend to slip between the bars and they find it difficult to walk on, not particularly because they won't walk over a void. | |

| Apr 10, 2019 at 13:40 | comment | added | Ynneadwraith | No problem ;) and yeah I like the idea of a vegetal land bridge. Rafts made from vegetation blown adrift by tropical storms are already a significant vector for transporting animals between islands (and continents!). Scaling that up would be very interesting :) | |
| Apr 10, 2019 at 13:33 | comment | added | Nyakouai | @Ynneadwraith Ah. My mistake, didn't know that. The idea of a vegetal bridge could still be workable, but is kind off off-topic. | |
| Apr 10, 2019 at 13:31 | comment | added | Ynneadwraith | For reference, the term 'land bridge' is usually used to denote an area of land that is normally beneath the surface of the sea, but as sea levels drop gets exposed allowing terrestrial animals to traverse it. Some examples during the previous ice age are the Bering land bridge between Eurasia and the Americas, and Doggerland which connected Britain to Europe. | |
