Mewgenics House & Breeding Simulator

Tool-first genetics planning. Estimate inheritance odds, flag inbreeding risk, and sanity-check house comfort before you commit a generation.

Step 1

Enter both parents

Paste or type traits for Parent A / Parent B (comma-separated). Prefix with Dominant: / Recessive: if known.

Step 2

Check risk + comfort

Pick relationship distance to estimate inbreeding risk. Then sanity-check overcrowding and house comfort.

Step 3

Make the pairing decision

Use the inherit forecast + risk tier to decide whether the pairing is worth the variance. Share the build link to reproduce the plan.

🧬 Breeding Simulator

Type traits like: Dominant: Giant Jaw, Recessive: Frail Bones (comma-separated).

Parents

This is a heuristic estimator for planning. If game data becomes exact later, you can swap the engine without changing SEO pages.
Inbreeding risk
Low
Relationship multiplier: 1.00× (planning heuristic)
Recommendation: safe baseline pairing. Focus on trait synergy and house upgrades.

Tip: keep traits short & consistent (e.g., “Giant Jaw”, “Frail Bones”). The tool matches by normalized text.

House comfort check

Comfort status
Barely OK
Total comfort: 0 (overcrowding penalty: -0)
Actionable advice
  • Keep rooms at 4 cats or fewer for stable comfort.
  • If you must overcrowd, compensate with comfort-heavy furniture.
  • Low comfort + high inbreeding risk = more “variance” (plan extra breeders).
Comfort logic here is a planning model. When you wire real house stats later, this UI stays the same.
Data note: this simulator is designed for decision support. If you later extract exact inheritance weights from game files, you can swap the math engine without changing URLs, SEO pages, or the user flow.

Why this isn’t a Wiki page

Wikis explain mechanics. Tools output decisions. This page produces a usable forecast (inherit odds + risk tier + comfort warnings) so you can act.

Close the loop

After you pick a pairing, validate RNG expectations in Luck Calculator and check mutation details in Mutation DB .

Quick notes

  • Dominant traits tend to pass down more reliably when present in a parent.
  • Recessive traits usually need both parents (or carriers). This tool uses a conservative model you can tune later.
  • Inbreeding is treated as a risk multiplier (planning heuristic) so you can avoid high-variance pairings.

This tool is designed so you can later plug in exact game weights without changing URLs, internal links, or page structure.
