In Mewgenics, randomness is your biggest enemy. Breeding is way to build a consistent stock of “Super Cats” (7-stat powerhouses with 5+ mutations), you must move away from chaotic hoarding and toward a Three-Room Rotation System.
Building the Perfect Cat: The Full Mewgenics Stat & Mutation Guide
To maintain a high-quality roster, rotate cats through three specialized environments:
- Breeding Room: High Stimulation for stat inheritance.
- Incubation/Storage: High Comfort and Mutation for passive growth.
- Dating Room: For pairing specific cats to ensure 100% breeding compatibility.
Essential Requirements
Before starting this rotation, ensure you have the following “P-Mart” and Tink upgrades:
- 3+ Rooms: Minimum (including the Attic).
- Totem Furniture: Crucial for Room #2 to prevent unwanted breeding.
- High-Tier Furniture: Focus on Stimulation (for inheritance) and Comfort (for stability).
- Tink’s Upgrades: All base upgrades should be unlocked.
The Three-Room Strategy
Room 1: The Breeding Suite
Goal: High-quality offspring production.
- Stats: Max Stimulation (20+), 5+ Comfort, Health, No Mutation furniture (prevents “pollution” of the gene pool).
- The Rule: Only place cats here that are already “In Love.” If one partner dies, remove both to prevent efficiency drops and accidental inbreeding.
- Pro Tip: Mark parents and their kittens with matching symbols to track lineage.
Room 2: The Vault (Incubation & Storage)
Goal: Growth and mutation development without the mess.
- Stats: High Comfort, High Mutation, low Health.
- Mandatory: Use a Breeding Prevention Totem.
- The Strategy: Store strays and kittens here. The high Mutation stat allows cats to develop new positive traits passively before they are selected for the breeding program.
Room 3: The Dating Lounge
Goal: Forced pairing.
- Stats: 2+ Comfort, 1+ Health.
- The Strategy: Move one high-stat kitten and one selected stray (or another kitten) here. Wait until they fall in love before moving them to Room #1. This ensures they only breed with each other.
Understanding Breeding Mechanics
The Inheritance Formula
Stat inheritance is heavily influenced by your room’s Stimulation level.
- At 0 Stimulation: 50% chance to inherit the better parent’s stat; 80% chance to inherit all parts; 50% chance per part otherwise.
- Stat Goal: Aim for “Complementary Parents.”
- Parent A (6/7/7) + Parent B (7/6/1) = Potential Kitten (7/7/7)
Gender & Sexuality Compatibility
| Combo | Result |
| Straight M + Bisexual F | High Success (Kittens) |
| Bisexual + Anyone | High Success (Kittens) |
| [?] (Ditto Cat) | Universal Donor/Receiver (Kittens with anyone) |
| Straight M + Gay F | Near-Zero Success |
| Gay M + Bisexual M | No Kittens |
Note on Inbreeding: Inbreeding increases the risk of Disorders (bad passives). If a cat becomes “Inbred,” simply breed it with a fresh Stray to reset the genetic line.
Progression Roadmap
Follow this tier list to scale your cattery from early game to the endgame.
Phase 1: Early Game (The Foundation)
- Focus: Constitution and Speed.
- Goal: Get these two stats as high as possible; ignore mutations for now.
Phase 2: Mid-Game (The 5-Stat Push)
- Focus: Max Speed/Constitution + 3 other stats above 6.
- Goal: Introduce Mutation furniture in Room #2 to start fishing for helpful passives.
Phase 3: Late Game (The “Super Cat”)
- Focus: 5 to 7 Max Stats (7s).
- Goal: Inherit 5+ desired mutations.
- Priority: Seek out the three “Reroll” mutations. These are the most powerful traits in the game and should be bred into every line.
Frequently Asked Questions
Q: Do I need high Stimulation if both parents are already Max Stat?
A: Not strictly for stats, but YES for mutations. High Stimulation increases the “Part Inheritance” chance, ensuring your 5+ mutations actually pass down to the kitten.
Q: Why use Strays instead of just breeding my best cats together?
A: Using Strays (especially those found via high Appeal) allows you to “clean” the gene pool and avoid the negative passives associated with inbreeding while filling in stat gaps.
