CatKai - Kitten Calculator

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.
