Questions and answers

No. It is a breeder's pedigree: your own written record of an animal's ancestors, as far as you know them, signed by you. Registration is done by a registry, on its own forms and terms, and some registries examine the animal in person. Every pedigree printed here says so at the foot of the page.

In this browser, on this device, in the browser's own IndexedDB storage. There is no server and no account, so nothing you type is uploaded. Clearing this site's data deletes the herd, so export a backup file from the herd page and keep it somewhere safe.

No. Names, ear numbers, photos, notes and your rabbitry name stay in this browser. Printing and saving a PDF happen on your own computer, and backup files are made inside the page and handed straight to you.

Rabbits, cavies and cats. The species sets the words used on the page and the print, such as buck and doe, boar and sow, or sire and dam, the identification label and the breed suggestions. You can type any breed or variety.

Three, four or five generations of ancestors behind the animal: 14, 30 or 62 ancestor boxes. Three generations is the common minimum for rabbit and cavy registration; four and five show more of the line.

Its box prints as Unknown, and every box behind it is left blank. Nothing is guessed. The page tells you how many ancestor boxes are known, so you can see how complete a pedigree is before you print it.

Wright's coefficient of inbreeding, computed from the ancestors recorded in your own herd. An unknown ancestor counts as unrelated, so the true figure can be higher than the estimate. It is arithmetic on your records, not a genetics or health assessment.

Linking a sire or dam that would make an animal its own ancestor is refused, with the names that form the loop. If a loop arrives in an imported file, the pedigree marks the box where it happens and stops walking that line.

Yes, through a spreadsheet saved as CSV. Export or copy your animals into a spreadsheet with one row per animal, save it as CSV, and match its columns to the fields here. Sires and dams are linked by ear number, then by name.

Yes. Everything here is free: the saved herd, litter batches, five generation pedigrees, your logo, CSV import, encrypted backup and the inbreeding estimate. There is no account, and no paid plan is offered at present.
