Care about this once animals are close enough to the daily crop and water route. Animal systems pay off when shelter, food, water, and product collection are checked together instead of scattered around the base.
Practical Use
Water Trough belongs in a care loop with troughs, shelter, water, and product collection. A compact animal area beats a larger scattered pen because happiness and collection checks happen more reliably.
Related Strategy
For animal planning, keep one care loop before scaling up. Shelter, food, water, happiness, and basket collection should be close enough that they fit into a normal farm pass.
Common Mistakes
Do not add Water Trough to a base where food, water, shelter, and collection are far apart.
Do not assume owning animals is the same as profiting from them; happiness and regular care are the useful part of the loop.
Do not transport animals to a new island until the receiving area already has the basics ready.
