Honestly, it's not the animals, it's their AI. I'll build them plenty of places for them to hide from guests but they don't bother actually using those spaces until I've already gotten 10 notices that their welfare is low and protestors are about to show up... why? Why can't they divert themselves to the nearest hiding place when the bar has dropped to 50%, why do they just wait until they're at a critically low level? Like they just decide to sleep out in the open and then complain that guests are looking at them; is there no way to make their AI say "only sleep in hidden areas if possible" or something?
