Show Preparation Comparison
Select two rats of similar quality but different genetic backgrounds. Enter each in separate shows and record win rates. Analyzing the outcomes highlights how specific genetics influence competitive success.
- Enter your highest‑quality rats first to increase win chances.
- Use wins to unlock breeders with new color specialties.

03 / THE GUIDE
NPC Breeder Trait Blend
Choose one trait from each unlocked NPC breeder and breed a line that combines them. Observe how the mixed genetics manifest in offspring, noting any unexpected color or pattern results.
- Visit each unlocked breeder to broaden genetic options.
- Combine traits from multiple NPCs for unique hybrids.

Outfit Impact Observation
Dress a rat with contrasting outfits and capture photos. Compare visual appeal and personal satisfaction, noting how styling choices affect your perception of the rat’s uniqueness.
- Match outfits to a rat’s color for striking photos.
