Or: The animal pen is great and all, but couldn't we have the option of keeping our pets elsewhere? I wanted my butterflies on the top floor and the piggies roaming free on the grass outside the pen (thus leaving me with a pen full of chickens to squeeze without interference). But nope, my released free-roaming pigs headed straight for the pen, and my butterflies practically flew through the floor in their haste to join them. Part of why I wanted a bigger house was to keep the animals seperate, so I wouldn't have to click 50 times to reach that final piggy that needed petting or that last unsqueezed chicken. Why does my animals seek out confinement?
