Yes, keep a health and weight log for your Aegean Cat, and expect it to earn its place. This is a breed shaped by life on the Greek islands, hardy, athletic, and famously fond of water and the outdoors, and that toughness creates the exact problem a log solves: an Aegean can carry on looking bright and capable while his weight, appetite, or energy drifts gradually enough that nobody in the household can say when it started. Written entries turn that vague feeling that he seems a bit quieter lately into dates and numbers a veterinarian can actually work with.
What an Aegean log should capture
Weigh him regularly, ideally on the same home scale and at a similar time of day, and record the figure rather than rounding it into a general impression. Alongside weight, note the things that explain it: how eagerly he eats and whether he finishes, how much water disappears from his bowl, his litter tray patterns, and his activity level, which for an Aegean often includes serious play, climbing, and supervised outdoor time. Add a line for coat and skin, because his semi-long, weather-resistant coat can conceal both weight change and lumps that your hands would otherwise find during grooming. A short monthly note on mood and sociability matters in this breed too, since an Aegean who stops greeting people at the door or abandons his favourite high perch is showing you a change worth dating in the log.
Reading seasonal patterns without panicking or shrugging
An active, outdoor-minded cat's weight rarely sits perfectly still across a year. Many Aegeans eat and move differently between hot months, when midday heat suppresses appetite and activity, and cooler months, when a thicker coat arrives and hunting-style play picks up. A log lets you compare this winter with last winter instead of comparing a sleek summer cat with his fluffed-up January self and alarming yourself. It also protects against the opposite error: blaming the season for a steady downward trend that continues across two seasons is how real problems get waved away. Look at the direction over several entries, not at single weigh-ins, and treat a change that persists, accelerates, or arrives with altered thirst, appetite, or litter habits as the point to book a veterinary appointment and bring the record with you.
Making the habit light enough to keep
Logs fail when they demand essays, so build yours around moments that already exist. Weigh him on the same day you do his regular grooming session, jot three or four short lines while his food is measured out, and take one clear side-on photograph each month to sit beside the numbers, because an Aegean's coat makes visual comparisons surprisingly useful.
When the log itself says call the vet
Some entries should trigger action rather than another week of watching. Book an appointment promptly for a clear, continuing weight loss despite a normal or increased appetite, a noticeable rise in drinking or urination, repeated vomiting or loose stools, or an Aegean who stops his usual climbing, playing, and greeting for more than a brief spell. A sudden weight gain with a swollen-looking belly, laboured breathing at any point, or complete refusal of food are same-day concerns rather than log-and-wait ones. The log's value in that moment is precision: instead of saying he has been off for a while, you hand over the dates, weights, and changes that help the vet decide what to check first. Storing that running record in KinsLe inside his Pet Passport keeps every entry together with his other records, ready to show at a routine visit, an urgent one, or a handover to a sitter who needs his normal patterns spelled out.
