Call A Pet Progression Guide: Economy and Progression After the Basic Loop

Once you can sneak into a zone, grab an egg from a guarded nest, carry it back to your safe zone and hatch it, Call A Pet stops being about one egg and starts being about what every egg turns into. Every pet you place earns money for you even while you explore, so everything past the beginner loop is about raising that income, moving faster, and feeding the loop with free eggs. The game's own systems name exactly what to improve next — here is the order they add up in.

1. Place every pet you hatch. Each placement permanently adds a passive earner to your base; collection size is the engine that funds everything else.
2. Repeat the loop across all five zones — Forest, Savannah, Desert, Snow and Volcano — to grow that collection. Bosses guard the nests, so every trip is a real run.
3. Fill each zone's Index. Discovering every pet in a zone unlocks a permanent income boost.
4. Upgrade rarity as eggs allow. Golden and Rainbow pets hatch with huge income bonuses; Cerberus, Anubis and Yeti are the named endgame Secret hunts.
5. Train movement in parallel. Ride pets and use treadmills — speed compounds over time and shortens every egg run.
6. Log in every day. Free cash and eggs feed the whole path no matter which milestone you're on.

The game doesn't mandate this sequence; it falls out of what each system is documented to pay. A pet only starts earning when it's placed, Index bonuses and rarity raise that income permanently, training speeds the trips that feed it, and dailies top up both ends.

The post-loop roadmap at a glance

First priority: place every pet you hatch

Placement is the least glamorous milestone and the most important. "Every pet you place earns money for you, even while you explore" — the earning starts when the pet is placed, and each placement keeps paying while you're off stealing the next egg. That passive cash is what the rest of your progression rides on. If you hatch something and hesitate about where it fits, place it anyway; every run you complete ends in the same question, and the answer is almost always "yes, one more earner." For the base side of this, the pet placement guide covers arranging your collection.

Second: widen the collection across all five zones

The game names five egg zones — Forest, Savannah, Desert, Snow and Volcano — with bosses guarding the nests. Every run is the same repeatable action: sneak in, steal an egg, carry it back, hatch it, place the pet. Each completed run permanently adds a passive earner, which is why breadth is the second priority after placement itself.

No entry requirements or fixed unlock order are stated for the five zones, so treat breadth rather than sequence as the goal: every zone you can reliably raid is a new set of pets to place, and later an Index to complete. If the stealing half of the run is where trips fall apart, the egg stealing guide focuses on that, and the zones overview puts the five areas side by side.

The two income upgrades: Index completion and rarity

Two separate systems raise what your placed pets earn, and they work differently — one rewards breadth, the other depth. The game promises both boosts without publishing their sizes, so there's no documented way to rank one above the other; run them side by side rather than betting on either.

Fill the Index, zone by zone

"Discover every pet in a zone to unlock a permanent income boost." The Index is the breadth system: it's keyed to discovering every pet in a single zone, which makes it a per-zone checklist you complete once — and the boost it unlocks is permanent. A practical rule is to finish whichever zone's roster you're closest to completing. The pet index tracks discovery, and the pets list shows what you're collecting toward.

Chase rarity: Golden, Rainbow and the Secret three

Rarity is the depth system. Golden and Rainbow pets hatch "with huge income bonuses", so a rarer hatch upgrades the same passive stream you already built — it's an income improvement, not a cosmetic one. Above them sit the legendary Secret pets: Cerberus, Anubis and Yeti, named by the game as endgame hunts. How they're obtained isn't spelled out in the game's description, so treat them as long-term targets to keep hatching toward, not a step with fixed instructions. The egg hatching guide covers the hatch itself.

Train movement in parallel

"Call your pet and ride it across the map. Run faster, jump higher, and train on treadmills to boost your speed." Riding is the immediate payoff; treadmills are the stated training stations. Speed matters to progression because every run in your loop ends with a carry back to the safe zone — faster legs shorten every single trip between nest and base.

Training also compounds rather than being one-and-done. In one gameplay stream from the game's beta period, the streamer observed that pets gain speed passively over time, but faster when the player actively trains — estimating passive gains at roughly half the rate of active training. That's a single streamer's estimate from a beta build, so expect exact rates to shift with updates; the takeaway that active treadmill and riding training is the quicker path held throughout the session. The movement guide goes deeper on training.

The free layer: daily logins and codes

"Log in every day for free cash and eggs!" Daily rewards are the one milestone with no order requirement: the cash feeds your income, the eggs feed your hatching, and both land regardless of which milestone you're working. Codes work the same way as an occasional top-up — the current list lives on the codes page.

Where the momentum points next

The order above follows the documented cause and effect: placements create the income, Index completion and rarity raise it permanently, movement training speeds every run that feeds it, and daily logins top up cash and eggs from outside. Keep the loop running, place what you hatch, and chase the permanent boosts first — when you're ready to push the earning side specifically, the cash guide is the natural next stop.
