Skin and coat come first in a Devon Rex diary
Skin and coat notes should lead a Devon Rex's weekly diary entry. His coat is short, fine, and wavy, with less protective hair than most cats, so his skin does more of the talking: note whether it feels dry, oily, or comfortable, whether you see flaking or reddened patches, and whether his whiskers and eyebrows look as sparse or full as usual. Record where he has been scratching, especially around the neck and ears, and whether a bath or wipe happened that week and how his skin responded. Because the Devon Rex coat breaks and thins easily, a note that a patch looks more exposed than last week is exactly the kind of early signal a diary exists to catch.
Ears deserve their own weekly line
Ear notes earn a separate line in a Devon Rex diary. Those large, low-set ears collect wax and debris more readily than smaller ears, so jot down whether each ear looked clean or waxy, whether there was an odour, and whether he shook his head, tilted it, or dug at an ear with a hind paw. Note any cleaning you did and what you found on the cloth. A single waxy week is unremarkable, but three weeks of increasing wax on the same side, recorded in your own words as it happened, gives a vet a timeline instead of a vague memory of him seeming ear-conscious for a while.
Appetite, weight and warmth in a fine-boned cat
Appetite and body notes matter because a Devon Rex is fine-boned under an oversized personality. He is typically a keen, almost mischievous eater, so record whether he finished meals eagerly, left food, or begged more than usual, and note treats or new foods tried. Run your hands over his ribs weekly and write whether he feels the same, leaner, or rounder, and weigh him if he tolerates the scale. Add a warmth note too: this lightly coated breed seeks heat and feels the cold, so record whether he has been burrowing, shivering, or avoiding his usual warm spots, which can say as much as a food note.
Energy, litter and the small behaviour changes
Behaviour and litter notes round out a Devon Rex's weekly entry. Note his play energy, since a Devon Rex is usually clownish and people-centred, following owners and fetching toys; a quieter week deserves a line even if nothing else changed. Record litter tray output in simple terms: normal, looser, harder, more frequent, or straining, plus any vomiting episode with what preceded it. Write down sneezes, eye discharge, or a change in his voice if they appear. These details look trivial singly, but written weekly they separate a one-day off moment from a trend that has been building for a month.
When the diary says book the vet
A Devon Rex diary should trigger a vet call when its lines start agreeing with each other. One week of scratching is a note; scratching plus ear wax plus a thinning patch is an appointment. Book promptly for repeated vomiting, refusal to eat beyond a day, breathing changes, a hot or sore skin patch, or head shaking that persists, and take the diary with you. Keeping the weekly entries in KinsLe next to his Pet Passport means the timeline you wrote at home sits beside his formal records when the vet reads it.
