(especially since animals can die anywhere and become liftables themselves)
but some things make no sense thus it has to be a bug. The only related report I could find is from 7 years ago!
It should not be possible to put down a container on a 200% slope or even a cliff!
There are even liftable items that cannot be build on ground that is too steep,
but once built nothing hinders you from putting it down on the same slope (example: Food Trough).
The slope I can maybe live with, but placing something into a cliff? This cannot be intended behaviour:
