Make room for animals
The public listing says base expansion lets you hold more animals. Expand when the game shows that capacity is relevant, then use its placement UI to add animals.
Pair capacity with income
Expansion and income upgrades are both named features. The listing does not state their prices or which should come first; compare your current constraints and the menu values.
Verify capacity in game
Check the displayed capacity before and after an expansion. Exact starting capacity and expansion levels are not stated in the public description.
