For Ragdoll breeders

Know what a pairing can produce — before it happens.

Ragdoll Calculator takes the genotypes of a dam and a sire and works out the probability of every possible kitten color, point pattern and carrier combination. Built around the loci that actually matter in the breed, with plain-English explanations and a cartoon preview of each result.

Color outcomes

Seal, blue, chocolate, lilac, cinnamon-adjacent amber and every red or cream variation, with the odds for each.

Pattern odds

Colorpoint, mitted, bicolor and high-white van results from the KIT white-spotting series.

Carrier awareness

Hidden chocolate and dilute carriers show up in the maths, so you know what a pairing could surprise you with.

Untested loci welcome

Anything you haven't DNA tested can be left as unknown — those loci are averaged into a best estimate.

    Set the X-linked orange status for the dam and sire.

  3. 3

    Pattern

    Choose each parent's white spotting, then calculate the litter.
