Between check-ups, an elderly rabbit's health story is written in small daily details that memory blurs within a week. A diary fixes those details while they are still useful, and its value comes from using one unchanging set of fields, recorded the same way every day, so entries can be compared across weeks. The set covers what goes in, recorded in plain amounts for hay, greens, and pellets alike; what comes out, with droppings noted by quantity and by size; the water level's daily drop; a weekly weight; and how the rabbit moves and seems each day. Add litter-tray photos, taken before cleaning, and you have a record a vet can read in minutes and trust.
Record the Same Fields Every Day
Write amounts in plain language you will actually sustain: hay as handfuls eaten or a topped-up rack mostly cleared, greens and pellets as the measured portions offered and what was left, water as a bottle or bowl level drop. Droppings deserve their own line: roughly how many, whether the size looks normal for this rabbit or smaller than usual, and whether they are round and dry or soft and misshapen. Mobility and mood take a sentence: hopping freely or reluctant to move, bright at feeding time or withdrawn in a corner. Weigh once a week on the same scale, at the same time of day, and enter the figure beside that week's entries. Keep entries short; a diary you maintain beats a detailed one abandoned after four days.
A Worked Entry Shows the Standard
A Tuesday entry might read: hay, two large handfuls offered, most eaten by morning; greens, a packed cup of mixed leaves, all eaten; pellets, two tablespoons, half left; droppings, plentiful overnight, normal size, round and dry; water, bottle down by about a quarter; mobility and mood, hopped to the pen door for breakfast, slower on the ramp by evening; weekly weight recorded on Sunday. Nothing in that entry needs equipment beyond a scale and a notebook, yet a vet reading a month of entries can see appetite sliding or weight drifting before any single day looks alarming. Photograph the litter tray at the same point each morning, before you clean it, and keep those photos in order with the written entries so quantity claims can be checked against the pictures.
Bring the Diary, and Act on Its Alarm
Small habits keep the diary trustworthy. Fill it in at the same point each evening, while the day's feeding and cleaning are fresh, rather than reconstructing several days at the weekend. Note anything that changed the inputs alongside the results: a new batch of hay, a different green, a hotter room, visitors, or a course of treatment the vet prescribed, because a droppings change that follows a diet change reads very differently from one that arrives uninvited. Shrinking droppings alongside reduced hay eating is a pattern worth phoning about promptly, since in an elderly rabbit it can accompany dental discomfort or a slowing gut, both possibilities the vet will want to examine rather than hear about weeks later. Keep the notebook near the pen, not in another room, and let anyone else who feeds the rabbit add entries in the same format so the record has no gaps.
Bring two weeks to a month of diary to every appointment, and hand it over rather than summarizing from memory; trends across that span are exactly what a vet needs to judge an elderly rabbit between check-ups. One alarm overrides the appointment calendar entirely: a rabbit eating notably less is an urgent vet contact the same day, not an item to store up for a routine visit, because a rabbit's gut depends on near-constant intake and appetite loss in an older animal can signal a problem that will not wait politely. The same urgency applies to droppings stopping or shrinking sharply alongside reduced eating. For the ongoing record, file each month of entries on KinsLe within Pet Passport, a records packet where diary, weights, and visit notes stay together for any vet who needs them.
