Getting stronger cats in Mewgenics is only half the battle. The real secret to dominating this quirky cat management game lies in systematically unlocking upgrades through NPC interactions. These permanent enhancements transform your entire gameplay experience, from expanding your inventory to growing your house into a sprawling cat paradise.
Every upgrade in Mewgenics connects to a specific NPC, and each one wants something different from you. Some crave mutated cats, others prefer battle veterans, and a few just want your elderly felines to retire in peace. Understanding these requirements early means you can plan your cat submissions strategically instead of scrambling later.
How NPC Upgrades Work
To unlock upgrades, you need to submit cats to NPCs. Each NPC focuses on a certain type of cat and rewards you with permanent benefits. You cannot buy these upgrades with currency, so working with NPCs is key. Keep in mind that submitted cats are permanently removed from your roster, so plan carefully.

Which Upgrades Should You Prioritize First?
Not all upgrades carry equal weight during early progression. Focusing on the right enhancements first creates a smoother gameplay loop that compounds over time.
Inventory Expansion from Butch
Your inventory fills up shockingly fast during exploration runs. Without expansion upgrades, you constantly face tough decisions about which items to discard. Butch accepts cats in batches of 20 that have participated in battles and reached new zones.

Send your weaker cats on zone exploration specifically to qualify them for Butch submissions later.
Inventory expansion benefits
House Expansion from Frank
More rooms mean more cats, and more cats mean faster progression across all NPC relationships. Frank wants retired cats that have completed their adventuring careers. Each expansion unlocks additional space for your growing colony.
Shop Upgrades from Tracy
Tracy unlocks collars, furniture, and food storage options that improve your quality of life significantly. She accepts cats that have aged to at least five years through multiple daily cycles. These shop items provide customization options you cannot find elsewhere.
Planning Your Upgrade Path
Upgrades in Mewgenics are connected. More inventory space lets you hold better items, helping cats survive longer. Surviving cats can retire, expanding your house, which supports more cats for faster NPC submissions.
Balancing focus across NPCs prevents bottlenecks. Aggressive players benefit from Baby Jack and Mystery Man. Breeding-focused players should prioritize Tink and Frank. Explorers get the most out of Butch and Steven. Your playstyle will determine the best upgrade order.
