 is like how much information is communicated when dogs are, you know, so we used to call it marking their territory, right? Which is this horribly reductionist way of thinking about, you know, the little sprays that your dog will be leaving as you go on your walk every day. And it's not marking territory, it's kind of saying, oh, hey, I'm here, this is who I am. And then when they sniff it, they're getting information about all the other individuals in that territory.
