i tried a scenario with 1000 and only 1 colonist, and wanted too see what would happen if they all went beserk, so i spawned a colonist ( the first one was stuck and a single cell with like, 100 or 500 pet animals) and a psychic animal pulse, and had the new colonist activate it, and because all the pets were sort of compacted at first, because there isnt enough space near the drop pods for them all too land in, a lot of them occupied one square, and when i activated the psychic animal pulser, theyall sorta expanded outward:

a lot of them are dying already.
I can't tell if this is less or the same amount of impressiveness as the thermal catspolsion.
Needs to be a video or gif :P
