The Parents: Names, Colours and Ages
Write down the sire and dam by the names or ID codes the breeder uses, their colours in the breeder's own terms — standard grey, beige, violet and the other recognised mutations — and their ages at the time of the litter. Chinchilla colour genetics are not decoration in this log: the parents' colours explain your kit's coat, tell you which pairings produced it, and become genuinely useful information if a vet ever asks about background or you speak to another breeder. Note whether the parents are the breeder's own animals or brought in, and how many litters the dam has had, since a hobby breeder who knows their lines will answer all of this happily.
The Birth Date and Litter Details
Record the exact birth date, not "early spring," because so much of chinchilla care is age-keyed: when the kit should have been weaned, when he was old enough to leave, and how his growth compares at each weighing. Add the litter size and whether your kit was a single or one of twins or triplets, since littermates share a start in life worth knowing about. Log the weaning date and the date you collected him as separate entries — they are often different days, and the gap between them tells a vet something about how settled he was when he moved.
Health Background Worth Asking About
Ask the breeder directly about both parents: any fur chewing, any dental trouble, any digestive sensitivity, and how long the line tends to live. Write down the answers in the breeder's words, including the reassuring ones. Chinchillas can live a long time, and the person answering questions about a ten-year-old's family history will be you, long after the breeder has retired their lines. Also note what the kit has been eating — the pellet brand or type and the hay — because an abrupt diet change on moving day is a common cause of a new chinchilla going quiet, and matching the breeder's food keeps the move smooth.
Your Baseline Entries on Collection Day
Close the log with the facts only you can capture: the breeder's name and contact details, the collection date, what you paid recorded privately if you wish, and your chinchilla's weight on arrival home as the baseline every future weighing is compared against. Add a photo from the first day. A single page with parents, birth, litter and baseline weight is the whole foundation of his records.
Keeping the Log Alive After Purchase
The breeder log is a starting page, not a finished file: add weights, vet visits and diet changes as they happen, and the parents-and-birth page keeps giving context to all of it. That is precisely the job of a KinsLe Pet Passport — your chinchilla's records gathered in one portable packet, beginning with the family history you captured at purchase and ready for every vet visit, holiday handover or new home that follows.
