About Mewgenics Tools

What this site is

Mewgenics Tools is an unofficial fan-made companion for Mewgenics players who want to go deeper than the base game explains. It provides interactive tools for the parts of Mewgenics that benefit most from calculation: multi-generation breeding paths, Mendelian trait probability, and class/ability team synergy.

Who it's for

Players planning a breeding strategy beyond the next litter — anyone chasing a specific trait combination, building a roster around class synergies, or just wanting to understand the genetics system before committing cats to a run.

How the tools work

All three tools run entirely in your browser. No account, no server, no data leaves your machine. Breeding and team state is stored in browser localStorage so it persists across sessions on the same device.

Breeding path results are heuristic, not exhaustive — the planner finds a good route, not a provably optimal one. Trait odds are exact Mendelian probabilities for single-locus dominant/recessive traits. Game data is sourced from the community and may lag behind patches; check the version note on each tool.
