CatKai - Kitten Calculator

Utilities

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

The genetics calculator built for serious cat breeders. Predict coat colors, detect carriers, and plan litters with confidence. CatKai is the genetics tool cat breeders have always needed — powerful enough for professionals, clear enough for anyone curious about feline inheritance. Whether you're planning a litter, evaluating a new stud, or trying to understand why a kitten turned out the way it did, CatKai does the math so you don't have to. WHAT CATKAI DOES Enter the traits or known genotype of a queen and a tom, and CatKai instantly calculates the probability of every possible offspring phenotype. It covers all major coat color and pattern genes, including: · Color: black, chocolate, cinnamon, and their dilutes (blue, lilac, fawn) · White spotting and full white (masking) · Tabby pattern: mackerel vs. classic · Agouti (tabby vs. solid) · Silver and smoke · Colorpoint (Siamese-type restriction) · Orange (sex-linked) · Long hair Results are shown as clear percentages with color labels — no genetics degree required. BREEDER MODE Unlock the full power of feline genetics with a Breeder Mode subscription: · Enter exact alleles for all genetic loci, not just observed traits · See every possible offspring genotype and its individual probability · Identify carriers of hidden recessive genes · Get warnings for impossible or contradictory genotype combinations · Distinguish mackerel from classic tabby, silver from smoke BUILT FOR BREEDERS CatKai lets you build a roster of your cats and save calculations for future reference. Compare pairings, track your breeding program, and make informed decisions — all in one place. The app follows Apple's design language: clean, focused, and distraction-free. It works fully offline — your data stays on your device. Breeder Mode is an auto-renewing annual subscription. Price and length are shown at the time of purchase. Your subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel your subscription in Settings → Apple ID → Subscriptions.
