I'm gonna pee on them.
Hey I wonder how the drones will deal with outdoor dogs or cats attacking the drone. Cats like to forget with birds and dogs are just.. weird.
Most birds don't have loud spinning whirring propellers.
Cats get scared by balloons and RC cars. I don't think they'll attack a drone.
Dogs will probably bark and whatnot, but I don't think they're likely to attack it. They too are quite fearful of mechanical things.
If there's any animal that might be a problem to it, then it's birds, which may collide with it in an effort to attack it.
Smaller birds, like swallows, are very defensive when they're nesting and will dive-bomb and swoop at animals and other things much larger than them.
But even then the machine might put them off.
And I suppose, depending on the height it flies at, insects may be a problem, as there are lots and lots of them up high in the air. I wouldn't think they'd cause much damage, but the risk is there that they get hit and jam smaller mechanical parts on the helicopter. But I think designers would take that into consideration.
