The Identity Page and Where Your Pig Came From
Open the file with the basics: your guinea pig's name, sex, color and rosette pattern description, approximate or known birth date, and where it came from, breeder, rescue, or shop, with contact details. Abyssinians are identified by their swirled rosettes, and a written description plus a photograph makes your pig distinguishable at boarding or if records ever need matching to an animal. Note its companions on this page as well: guinea pigs are social animals, and who your pig lives with is core information, because a companion's illness, or loss, changes this pig's health and behavior picture immediately.
Weight Records: The Single Most Useful Habit
Weigh your Abyssinian regularly, weekly is a good rhythm for an adult, and log the result with the date. Guinea pigs hide illness instinctively, and a downward weight trend is often the first objective sign that something is wrong, appearing before appetite changes are obvious in a shared cage. Record the scale you use and weigh at a similar time of day for comparability. A stable line is reassuring; a steady slide, or a sudden drop, is your cue to book a vet visit and bring the log, because 'he seems a bit lighter' persuades nobody, while six weeks of numbers tell the vet a story at a glance.
Diet Records With Vitamin C in the Spotlight
Guinea pigs cannot make their own vitamin C, so the diet log is a health record, not a shopping list. Write down the pellet food used, the hay type, and the daily vegetables, noting which vitamin C-rich vegetables are in rotation and how often they appear. Record changes too: a new pellet, a dropped favorite vegetable, a week of poor hay. If your pig ever shows stiffness, reluctance to move, rough coat, or slow healing, the vet's first questions will be about vitamin C intake over time, and a written log answers accurately instead of relying on your impression that it 'usually gets peppers.' Note any supplements only if your vet has advised them, with the advice recorded beside them.
Coat and Skin Notes for a Rosetted Breed
The Abyssinian's rosettes look charming and hide problems efficiently. Keep brief coat notes: when you part the fur during grooming, what the skin looks like, any flaky patches, scratching, hair loss, or lumps, and when you noticed them. Skin trouble in guinea pigs can smolder under a dramatic coat for weeks, so dated observations turn a vague worry into a timeline a vet can use. Record grooming sessions too, including any tangles worked out and how the pig tolerated handling, since a pig that suddenly resists its usual grooming may be telling you its skin hurts.
Vet Visits, Treatments, and Dental Checks
File every vet visit with its date, reason, findings, and any treatment given, and keep a note of your vet's details and the emergency route at the front. Ask for teeth to be part of routine checks and record what was found; guinea pig teeth grow continuously, and eating changes, drooling, or dropping food between visits should be written down when you spot them, not reconstructed at the next appointment. If your pig lives with a companion, cross-reference illnesses: a respiratory episode or skin treatment in one pig is relevant history for the other, and paired notes make that connection visible.
Housing, Companions, and Life Events
Round out the file with the life record: housing setup and changes, bedding type, companion introductions, separations, or bereavements, and any boarding or sitter stays with the sitter's notes attached. These events explain behavior shifts, appetite dips, and stress signs that otherwise look mysterious in the health notes. Keeping the whole record in KinsLe's Pet Passport means the weight log, vitamin C diet history, and vet notes stay in one packet that travels to appointments and sitters with your Abyssinian, rather than living in a drawer of disconnected scraps.
