Log the Same Five Things at the Same Times
A daily log for a Devon Rex stays useful when it is short, fixed and timed to the day you already live. Record food offered and food actually eaten at each meal, a water and litter note, one line on energy and mood, and anything you noticed about skin, coat or ears. Attach the logging to breakfast and the evening feed so it happens while the details are still fresh, and keep each entry to a line or two.
Resist adding fields week by week. A Devon Rex log with twenty boxes gets abandoned by Friday, while five honest lines a day build into months of evidence about what normal looks like for your particular cat.
Track Appetite in a Devon Rex's Own Terms
Appetite logging matters for a Devon Rex because this breed is food-motivated and usually eats with enthusiasm, so a cat who walks away from a favourite meal is sending a clear signal. Note whether meals were finished, partly eaten or refused, and whether enthusiasm was normal, keen or absent. Write what was served as well, because a refusal on the day a new food appeared means something different from a refusal of a long-standing favourite.
Note begging and scavenging too. A Devon Rex who suddenly raids bins or cries for food an hour after eating has changed behaviour, and a log that only records bowls would miss the change entirely.
Weigh Weekly, on the Same Scale, the Same Way
Weight belongs in a Devon Rex log weekly rather than daily, because a small fine-boned cat's readings bounce with litter visits and meal timing. Weigh at the same time of day, ideally before breakfast, using a kitchen or baby scale your cat will sit on in a carrier or box, and record the method alongside the number so future readings are comparable.
Plot the numbers as a simple run rather than judging each one alone. A Devon Rex should feel lean with a visible tuck, and a slow slide across several weeks, in either direction, is the finding worth raising at the next vet visit. A single odd reading usually deserves a re-weigh, not worry.
Add the Skin and Ear Lines This Breed Needs
A Devon Rex log earns a breed-specific section because the sparse wavy coat and large open ears show changes early. Once or twice a week, note ear wax build-up and whether you cleaned the ears, any greasy patches along the back or chin, and whether the coat felt thinner anywhere. These cats can be prone to oily skin, and a log line saying ears needed cleaning twice this week, up from the usual once, is exactly the kind of early pattern that is invisible without notes.
Also record warmth-seeking changes. A Devon Rex who suddenly abandons sunny spots and hides under blankets, or the reverse, has shifted behaviour in a way worth one plain line in the log.
Turn the Log Into Something Your Vet Can Use
A Devon Rex daily log pays off when you summarise it before appointments: appetite mostly steady, weight down slightly across six weeks, ear cleaning needed more often. Bring the summary and the raw log, and let the vet see both. If appetite drops for more than a day, weight falls noticeably week on week, or skin and ear changes arrive alongside lethargy, contact the vet promptly rather than logging and waiting.
Kept this way, the log stops being a chore and becomes your cat's own baseline. Storing it with KinsLe Pet Passport keeps a Devon Rex's care, appetite and weight record in the same portable packet as his health documents, ready for any vet, sitter or boarding handover.
