About
Pedigree and breeding records built specifically for fancy rats — with AFRMA-standard fields and color prediction from AFRMA's published WHAT IF chart.
No more retyping color names into a free-text box. No more keeping a paper AFRMA pedigree form in one binder and a spreadsheet in another. RatteryLog is a purpose-built iOS app for fancy rat breeders and rattery keepers.
【What You Can Do】
▷ Rat Profiles
Register every rat with AFRMA-standard base color, marking, coat, ear, and tail fields (plus a custom color field for anything outside the standard list) — alongside sex, birth date, status, acquisition source, and photo. Free up to 25 rats total, counting rehomed pups (deleting a record frees a slot).
▷ Auto-Built Pedigree Tree
Link a sire and dam once, and the pedigree tree builds itself — up to 4 generations back. An ancestor you don't have full records for can still carry a name-only note, and a repeated common ancestor is flagged automatically.
▷ Color Prediction
Pick a sire and dam and see the offspring colors AFRMA's own official WHAT IF chart predicts. Transcribed and cross-checked cell by cell against AFRMA's published chart — nothing invented. It is a reference tool, not a guarantee of what any litter will look like.
▷ Pairings, Litters & Predicted vs. Actual
Log a pairing and get an automatic gestation due-date window. Record a litter's live and stillborn counts, then register pups in one batch form (name and sex; color and other fields can be added later on each rat). If you ran color prediction on the pairing, you can compare that forecast with the colors actually born.
▷ Placement Records
Track where every pup went — destination type, price, handover date, destination note, and a follow-up note — built around rehoming, not livestock sale.
▷ Pedigree & Litter PDF Export
Export a formal pedigree certificate or a litter report as a PDF, ready to print or hand to a new owner.
▷ Share Cards
Generate a new-litter card, a pedigree card, or a rattery-stats card and send it from your device's share sheet. Free with a small watermark — Pro removes it and adds your rattery's own mark and accent color.
▷ Color Reference Chart
Browse every AFRMA WHAT IF combination in a searchable in-app reference — no more digging through a printed chart.
▷ Achievements
8 milestones track your progress, from registering your first rat to spotting a common ancestor in a pedigree.
▷ ZIP Backup & Restore
Export every record as CSV plus your photos in one ZIP file, and restore from a backup without overwriting what's already there. Free for everyone.
