Understanding the NPC‑driven upgrade path lets players optimize cat management, reducing grind and extending the game’s longevity. Efficient upgrade sequencing directly impacts progression speed and overall player satisfaction.
Mewgenics blends creature collection with RPG mechanics, and its upgrade ecosystem is anchored by seven distinct NPCs. Each character—Butch, Baby Jack, Dr. Beanies, Frank, Tracy, Tink, and the Mystery Man—offers a unique benefit, from extra storage slots to new rooms and specialized breeding insights. The requirement structures encourage players to diversify cat activities: battling for zone‑specific cats, sustaining injuries for medical quests, or simply aging cats to meet senior thresholds. This design creates a feedback loop where strategic cat handling unlocks tools that, in turn, streamline further cat management.
Early‑game efficiency hinges on targeting upgrades that alleviate immediate bottlenecks. Butch’s inventory expansions prevent item overflow, while Frank’s house extensions accommodate a growing feline roster. Tracy’s shop introduces high‑value accessories and storage solutions that become essential once the basic inventory is saturated. By focusing on these three NPCs first, players can maintain a steady flow of resources, reduce the need for constant trashing, and keep breeding cycles uninterrupted. The game rewards players who plan submissions ahead of time, turning mundane cat retirement or injury into purposeful progression steps.
In the long run, the deeper upgrades from Dr. Beanies, Tink, and the Mystery Man shape the meta‑game. Invention side quests from Dr. Beanies generate lucrative loot, Tink’s breeding data refines genetic predictions, and the Mystery Man’s item recovery mitigates loss from combat fatalities. Together, they foster a layered strategy that keeps players engaged beyond the initial novelty. This NPC‑centric upgrade model not only differentiates Mewgenics from other pet simulators but also drives community discussion around optimal cat pipelines, enhancing the game’s replay value and fostering a dedicated player base.

Mewgenics has several upgrades tied to the different NPCs that you can unlock on your adventures.
Upgrades in Mewgenics come in different types, and there's relative freedom in terms of what you want to unlock first. The process of unlocking different upgrades is also unique, as they're tied to all the NPCs. Let's find out how to obtain all the upgrades.
The table below has all the information you'll need to unlock the various upgrades.
NPC
Requirements
Upgrades
Butch
You'll need to submit cats that have reached new zones. While the requirements are easier at the start, they increase as you gain access to more zones. Butch always takes cats in batches of 20 (and they must have taken part in battles across the previous zones).
You can increase your inventory space with the upgrades. Having the extra space will enable you to store more items without having to send them to the trash.
Baby Jack
You have to submit cats that have injuries. The injuries could have been a result of battles, or your cats might have fought in the home
Baby Jack will offer different furniture for you to acquire. The list of options goes up as you get more upgrades.
Dr. Beanies
If you have a cat with mutations or birth defects, you can submit them to Dr Beanies. He also accepts cats with disorders and parasites, and you have to submit in batches of five.
Dr Beanies will provide you with Invention side quests, which will fetch your loot and coins as rewards. However, you can have a maximum of five of these quests at any give point in time.
Frank
You have to submit your retired cats to receive the upgrades. Retired cats refer to those who have completed an adventure (area/zone doesn't matter).
Frank allows you to expand your house by unlocking more rooms. The more rooms, the more cats you can keep.
Tracy
Tracy only accepts cats that are five years or older. In simple words, you'll need to submit cats that have advanced through five or more daily cycles.
You'll get more purchasable options at her shop. These can be collars, unique furniture, or a food storage box.
Tink
Tink will only accept kittens. Getting kittens is relatively simple as long as you have cats who will mate with one another.
Breeding the best cats require information that you won't have at first. Getting upgrades from Tink will help you to get more data about your cats. This will include information like their sexual orientations, libido, and more.
The Mystery Man
Some of your cats will die in battles, and The Mystery Man will help return some of the items you have lost. He also does the same if a cat dies in your home.
Getting the upgrades will fetch you more items in return.
Steven
Steven requires you to clear specific zones.

The first set of upgrades to go for will be the ones offered by Butch. Items play an important role, and you'll find plenty of them. Your inventory will fill up pretty soon, and increasing the inventory space is important.
Secondly, getting upgrades for Frank and Tracy is also important. Tracy offers some valuable items/options in her shop, which include the colourless collar. Having a larger home is a necessity after the early game, and that's where Frank's upgrades come in handy.
