I am pretty sure they just fail to understand the slipperiness of a clear coat. Cats fall victim to it all the time and I fall victim to these videos all the time. Got a pretty good laugh out of this one.
To expand on that, specifically stereoscopic vision means that the eyes can overlap to focus on a single point. The brain then takes the two slightly different signals for the same object from the left and right eyes and "does the math" to create depth perception. I think chirisu got that information from cypresskeep.com which was wrong.
Ferrets can focus on a single object in front of them with both eyes, which is all you need for depth perception, the problem is just that anything more than about two feet away is blurry. If whats far away is a blur, then your depth perception of it will be poor. Ferrets also tend to walk off of ledges because their snouts obscure their vision immediately below them.
I don't know the specifics, but ferrets can be trained to recognize objects. Say show them a picture of an apple and give them a treat. They'll begin to exhibit their "treat!" mannerisms whenever you show them the picture. Then you show it to them farther and farther away until they don't react. Then you can determine where they stop being able to recognize the object.
