'She vomits a lot' starts no useful conversation at the vets, because a lot can mean twice weekly or twice yearly, hairballs or food, trivial or significant. A simple episode log converts that worry into evidence: dated entries, kept in the same format every time, that let you and your vet see frequency, type, triggers and recovery at a glance. The log never diagnoses anything itself — it equips the professional conversation with facts your memory would otherwise blur.
The Four Fields Every Entry Needs
Record exactly four fields for every episode, no more and no fewer, because consistency is what makes months of entries comparable. First, the date and time. Second, the type of episode, judged by what came up: a true hairball — a compact, tubular wad of fur — food brought up barely digested, or liquid or foam carrying little solid material. Third, her food and activities during the hours before it happened: the meal, any new food, treats, fast eating, heavy grooming, play or stress you noticed. Fourth, how she was afterwards: whether she ate her next meal, drank normally, used the litter tray as usual, and returned to her normal self promptly or stayed quiet. Keep the format identical in a notebook or phone note kept where episodes happen, and write the entry within the hour, while the details are still visible rather than reconstructed at night.
A Worked Example With Real Entries
Two entries in the finished style show the level of detail that helps. Entry one — Tuesday, 6:40 pm. Type: hairball, a compact tube of fur. Beforehand: groomed heavily through the afternoon after a long nap, then ate her usual evening meal about an hour before. Afterwards: drank water soon after, used the tray normally that evening, and ate breakfast next morning with her usual enthusiasm. Entry two — Friday, 7:15 am. Type: undigested food, recognisable pieces brought up minutes after eating. Beforehand: ate breakfast very fast after an energetic play session, having finished the whole bowl in one go. Afterwards: settled within the hour, showed interest in food again by midday, and drank and used the tray normally all day. Neither entry alone means much; together, in this format, they already separate a grooming-related hairball from a speed-eating episode, which is precisely the distinction a vet will probe.
Reading the Log for Patterns, Not Panic
Review the log monthly and look for shape rather than single events. A single hairball now and then is a common event for cats, particularly longhaired ones and during heavy shedding, so a scattered hairball entry every few weeks, with normal recovery each time, is a pattern to mention at a routine visit rather than an emergency. What deserves a prompt vet discussion is change: episodes clustering closer together, vomiting becoming more frequent than hairballs, repeated liquid or foam episodes, or recoveries that stop being normal — appetite down, drinking changed, tray habits altered, energy low. Patterns tied to one food, one time of day or one behaviour, such as fast eating, give your vet a concrete starting point. Never let the log delay a visit when an episode itself worries you; frequent vomiting is not normal for cats, whatever the log eventually shows.
Taking the Log to the Vet
Bring the whole log to the appointment, not a summary, and let the vet read the entries directly — the type descriptions and recovery notes answer questions you would not think to volunteer. Expect the conversation to cover frequency trends, diet, grooming and shedding, eating speed, and what else has changed at home, and expect the log to shape decisions about monitoring, diet adjustments or further checks. Between visits, keep the log with her other health papers so any vet, sitter or family member can see the same record. After every visit, file the vet's comments beside your dated entries in KinsLe, since Pet Passport keeps that combined history portable between home, sitter and clinic.
