There could be a greeble up there. Don't need a bunch of invisible creatures scurrying about
You should also consider what your dog considers. They can hear and smell things you can't, while they always try to consider what you pay attention to. Intetspecies teamwork makes the dream work :3
I recently learned that cats are drawn to resemble anime girls. You can see this in their face shape and eye position. It blew my mind.
I did that once, the cats were staring out the window with wide-open eyes, so I joined in to see what the hubbub was all about... and there was a silver fox on the porch, staring back at us.
There we all stood, all frozen in place for a while, like some sort of "Mexican standoff".
Never again.
don't have an exact source but found it on https://infosec.exchange/@catsalad/112399140750326501
if I had to consider what my cat considers, I will be considering mass murder and world domination
