What to know
- Prioritize base stats over total stats, as only raw values up to 7 pass to kittens from parents.
- Donate kittens to Tink early to unlock visibility on base stats, orientations, and inbreeding risks.
- Organize rooms by function: core breeding with high stimulation, reserves, run prep, and mutation integration.
- Use food aggressively between runs to maximize breeding cycles and diversify gene pools.
Master breeding in Mewgenics by engineering cats with perfect sevens across stats, desirable mutations, and passives. You start blind to key details, but unlocking tools and structuring your house turns strays into dynasty studs.
| Aspect | Key Pointers |
|---|---|
| Core Goal | Breed kittens inheriting max base stats (7s) from parents’ bests |
| Main Stat | Stimulation: Boosts high-stat and passive inheritance |
| Essential Unlock | Tink donations: Reveals base vs. bonus, gaydar, aggression |
| House Must | Multiple rooms for breeding, reserves, runs, mutations |
| Risks to Avoid | Inbreeding (check family trees), low comfort fights |
| Pro Tip | Feed heavily post-run; integrate strays for fresh blood |
Base stats drive inheritance
Kittens pull each of their seven base stats—strength, dexterity, constitution, intelligence, wisdom, charisma, luck—independently from either parent. Aim for the higher value per stat, so pair cats with complementary 7s, like one strong in strength and the other in dexterity.

High stimulation in breeding rooms raises the odds of kittens grabbing those peaks, plus inheriting passives, which stay rare without it. Mutations often net positive, like +2 to one stat and -1 to another, and pass down too.
Unlock Tink for breeding intel
Rush kitten donations to Tink right away, as early unlocks change everything. Your first donation gets a useless bow, but every 10 after reveals layers: base stats first, then inbreeding flags, sexual orientations via flags, libido levels for mating drive, aggression tiers, and love-hate icons between cats.
| Donations Milestone | Unlocked Feature |
|---|---|
| 1 kitten | Fancy bow (skip) |
| 10 kittens | Base stats visible |
| 20 kittens | Inbreeding indicator |
| 30 kittens | Orientation & libido |
| 40 kittens | Custom marking icons |
| 50 kittens | Aggression levels |
| 60+ kittens | Love-hate relations (then coins) |

Housing stats shape outcomes
Furniture from Baby Jack sets room vibes, except appeal which buffs house-wide stray quality. Pump stimulation and comfort in breeders to favor inheritance over fights. Health extends lives and cures mutations overnight; mutation stat spawns more traits.
| Stat | Effect | Ideal Room Use |
|---|---|---|
| Stimulation | Higher parent stats/passives to kittens | Core/secondary breeding |
| Comfort | Breeding vs. fights (each cat/mess drops it -1) | All rooms, high to avoid losses |
| Health | Longevity, mutation cures | Reserves, defenders |
| Mutation | New traits (mostly +) | Mutation integration room |
| Appeal | Better strays house-wide | Everywhere for 7-stat inflows |
How to set up your perfect house strategy
Dedicate rooms smartly once unlocked. Make sure to control inflows via food-fed breeding and strays.

Room 1 (Core breeding): High stimulation/comfort. House your top stud (multi-7s) with compatible mates. Breed, evaluate kittens, retire parents to avoid inbreeding.
Room 2 (Run dump): Medium comfort. Toss injured or run-ready cats here—they gather resources without tainting genes.
Room 3 (Reserves): High health/comfort. Park retired high-stat cats for defense or future crosses. Add appeal anywhere for elite strays.
Room 4 (Mutation lab): High mutation. Mix perfect-stat cats with stray mutants or passives. Breed to fuse 7s + traits like +2 strength.
Room 5 (Secondary breeding or arena): High stimulation or low comfort. Cross lines from room 1 for diversity, or spark fights for winner stat boosts.
Spend all food post-run—200 is easy to farm. Introduce strays to dodge inbred defects; family trees spot relations fast.
How to breed step by step
Follow this to stack 7s, mutations, passives.
Step 1: Prep visibility
Donate 10+ kittens to Tink for base stats. Mark and check orientations/libido.
Step 2: Stock core room
Pick stud with most 7s, pair with complementary high-libido mate (opposite or bi). Max stimulation.
Step 3: Feed and wait
Dump food for max litters (1-2 kittens each). End day.
Step 4: Evaluate newborns
Mature kittens show base stats. Cull inbred/lows to Tink/runs; promote 7-gainers to stud status.

Step 5: Rotate and diversify
Swap spent parents to reserves. Integrate top stray (appeal helps). Cross to room 5 for hybrids.
Step 6: Fuse traits
Room 4: Breed perfect 7s with mutation/passive carriers. High mutation/stimulation yields elites.
Step 7: Iterate endlessly
Feed, breed, select. Full-7s with traits emerge; run them for endgame clears.
| Common Rewards | Source | Benefit |
|---|---|---|
| Base stat 7s | Parent inheritance + stimulation | Perfect baselines |
| Mutations (+2/-1 or pure +) | Room stat, events, items | Stat spikes, uniques |
| Passives | Rare inheritance + stimulation | Run-defining skills |
| Coins (25x) | Tink 60+ | Furniture buys |
| Stat boosts | Fight wins (low comfort) | Surprise upgrades |
| Cured mutations | High health overnight | Clean genes |
