Priced at $40 USD, the Fire TV Stick is a bit more expensive than Google's $35 Chromecast, but $10 cheaper than the already-affordable Roku Streaming Stick âlike other typical set-top boxes, the standard Fire TV is available for $100.
The precise question was: Is a dog's mouth cleaner than a human's? The answer to that is no, too, and basically for the reasons you've already cited. As we all know, dogs aren't particularly fussy about where they put their tongues or what goes into their mouths.
The first thing the researchers noticed is that cats and dogs drink very differently. Both animals extend their tongues and curl them back toward their chins as they approach water. But dogs use their bent tongues as a ladle, spooning water into their mouths. The scoop of sorts created by the cats' tongues stayed empty. Instead, cats touched only the top surface of their tongue to the water. Once a cats' tongue touches the surface, it draws it back at a rate of almost four laps per second.
