Cash per second comes from four places: the rebirth-point Upgrade board, the paid multiplier passes, the collection and merge systems, and weather mutations. Read the rate your own pen pays before and after each change instead of copying a number from someone else's session.

Each lever was read from a dated creator recording: the August 15, the September 1, or the October 14, 2026 session.
The Upgrades board is where the permanent rates live: Cash Boost raises the cash multiplier, Multi Roll adds roll pedestals at once, Luck Boost raises luck, Gems Per Min adds passive gems, and Rebirth Buttons raise what one reset pays. Auto Roll sits on the same board for 10 points. Every one of them is bought with rebirth points, so they compete with each other and with the Floors menu.
A separate shop sells cash multiplier passes beside the free board. A creator session published August 15, 2026 bought 1.5x and 2x cash tiers and the on-screen money label moved to 4x; the September 1, 2026 session bought the 1.5x tier for 27 Robux. The official store only lists two passes, Max Rebirth and Auto Collect, so treat the multiplier tiers as in-experience purchases rather than fixed store items.
Four systems change income without touching the board: the Index pays a permanent cash bonus as you collect distinct pets, merge turns five identical pets into a gold pet, the offline Fuse Machine builds pets with their own cash per second, and weather mutations raise a pet's output during the event.
Walk up to a placed pet and read the cash per second on its own label. That reading is the before value for every change below.
Cash Boost moved the multiplier from 1x to 2x for a single rebirth point in the August 15, 2026 recording, which is the cheapest rate change seen on screen. Buy Auto Roll early only if you want the button pressed for you.
Collecting distinct pets pays a permanent cash bonus: 5 pets for +5% cash and 3 Gems, 10 for +10%, and 20 for +15% in the October 14, 2026 recording. A cheap pet you do not own yet is worth more than a duplicate.
Merge takes 5 identical pets plus 50 Gems for a guaranteed gold pet and the machine keeps working offline: 5 Goat + $50M + 75 Gems returns a Cerberus at $40K/s in 5 minutes, and 3 Bear + $500M + 200 Gems returns a Qilin at $500K/s in 10 minutes.
Check which of the four levers you have actually bought. A pen with no Cash Boost, no Index bonus, and no merge is running at its base rate.
A gold pet doubles that pet's own rate, not the zoo total. A Gold Chicken read $30/s in the October 14, 2026 recording, and the player judged 50 Gems badly spent on it.
The Fuse Machine is built to run offline. Start the timer, then collect when the countdown is finished instead of standing in the room.
Five identical pets reads as a guaranteed 100% merge. Two or three pets showed a much lower chance in the same recording, which can burn the Gems for nothing.
Cerberus needs five Goat at $140K each and Qilin needs three Bear at $4M. A session that went after the recipe panel without the base pets never started a single fuse.
A pedestal pet survives only until the next roll. Keep the cash for the pet you are chasing, and set the Auto Roll filter for every rarity you can afford.
The Upgrade board (Cash Boost, Multi Roll, Luck Boost, Gems Per Min), the paid multiplier passes, the Index collection bonus, merge gold pets, Fuse Machine pets, and weather mutations. All six were visible on screen across the August 15, September 1, and October 14, 2026 recordings.
Cash Boost is the cheapest rate change on the board and applies to every pet you place. Auto Roll costs 10 points and removes manual pressing. Space is a separate purchase in the Floors menu, where Floor 2 costs 100 points.
The official experience description says the zoo earns money offline, and the Fuse Machine timer runs offline by design. The size of any offline cap is not published, so no cap number is claimed here.
The Sell stall paid $15 for a Dog, $50 for a Koala, $100 for a Bat, $1.5K for a Turtle, and $5K for a Capybara in the October 14, 2026 recording, against backpack capacity of 250 pets. Selling clears space for rate; it does not raise the rate itself.
