What an Animal upgrade does
Upgrade an Animal when you need more Cash from the collection you already own. The game says upgrades boost income. Check the cost and the income displayed for that Animal, make one purchase if it fits your plan, and compare the result before buying another level.
Before buying, inspect the Animal’s displayed earnings and the upgrade option. If the interface shows a projected gain, compare it with the cost and with the other choices available right now. If it does not, note your current Cash rate and check it again after one purchase. That small comparison helps you decide whether to continue upgrading or put Cash toward another goal.
Upgrading an Animal is especially useful when your Base has room for its current collection but your income is too slow for the next meaningful purchase. It can also be appealing when the route to a better Egg is unreliable. Your existing Animal is already earning; improving it may be a simpler step than chasing a distant hatch.
Compare upgrades with expansion
Base expansion has a different role: the game says it lets you hold more Animals. If you are at capacity, extra income from one upgrade may help, but it will not create room for the next hatch. Inspect the price of expansion and decide which problem is more urgent. If you can still keep several more Animals, the capacity purchase may wait while you improve earnings.
Do not use a universal priority list without seeing your account. One player may be blocked by a full Base, another by slow income, and another by limited flight reach. Spend to remove the bottleneck that is stopping your next complete Egg-to-Animal-to-Cash loop.
| Your bottleneck | First option to inspect |
|---|---|
| Cash grows too slowly | An upgrade on an Animal that already earns well. |
| The Base has no room | Expansion before another hatch. |
| Useful Eggs are out of reach | Flight progress, funded by Animal income. |
| You have room and a reachable better Egg | Hatch it, then compare its income with an upgrade. |
Use one purchase as a test
If you are uncertain, make one affordable upgrade and observe what changes. Check the Animal’s income and your overall Cash display. If the gain is clear and another upgrade is reasonably priced in the live interface, you have evidence for continuing. If the gain is small compared with a Base expansion or Egg opportunity, save for the other option.
This test also protects you from stale advice. Upgrade costs and effects may shift as the experience changes. Your own before-and-after values are current for your account, while a screenshot from an old guide may reflect a different version. For a broader earning plan, read how to earn Cash. For the capacity side, see Base expansion.
FAQ
Do Animal upgrades increase Cash income?
Yes. The official game description states that Animal upgrades boost income. The exact effect should be checked in game.
Which Animal should I upgrade first?
Compare the current earnings, upgrade cost, and expected gain shown for your own Animals. No official universal ranking is published.
Should I upgrade or hatch another Egg?
If you have room and a reliable route to a useful Egg, compare that hatch with the upgrade. If the route is unreliable, improve a current earner.
Will upgrades increase Base capacity?
The public description assigns capacity to Base expansion. Check the live upgrade text before assuming an Animal upgrade changes space.
