Two weeks away is long enough for her weight to shift and short enough for a shift to be missed completely without figures. A fresh weighing just before departure turns the vacation into a measured stretch: one clear entry before, any entries during, and one on your return, all in the same series and all read together.
Log the Pre-Trip Weight as the Anchor Entry
Weigh her in the last day or two before you leave, not two weeks earlier, and add the entry to a running, dated record of her weights, always weighed on identical scales under identical conditions, so anyone can see at a glance which way the trend runs. That pre-trip entry is the anchor: every later judgment about the vacation period compares against it, so it must be taken her usual way, on her usual scales, at her usual point in the day.
Write the method beside the anchor entry in words a stranger could follow: which scales, where they stand, whether she is weighed in her carrier, and when in the day. A method described only as the usual way means nothing to a sitter who has never seen the usual way performed, so spell it out once, properly.
Brief the Carer and Settle the Terms in Writing
Tell the person feeding her where the list lives and what you want recorded: any weighing done during the stay, entered with its date, plus a simple daily note of how she ate. If a paid sitter, boarder, or cattery is involved, get the agreed terms confirmed in writing before you leave, covering the dates of the two-week vacation, the pay or daily rate, the visits or care each day, and what happens if your return is delayed.
Be clear that a mid-stay weighing only helps if it copies the home method. A figure taken on different scales, after a meal, belongs in the daily notes as an observation, not in the dated list, because one off-method entry can bend the apparent trend of the whole series. On your return, weigh her the usual way before you judge anything, and enter that figure next.
Ask the carer to keep the food side of the story with equal care: the same food, the same measured amounts, and a note whenever a meal is refused, halved, or supplemented by someone being kind. Weight entries without feeding notes invite the wrong conclusion on your return, because a two-week vacation often includes extra treats from a household that adores her. If she boards instead of staying home, the same anchor logic applies at the facility: your home weighing before, their dated notes during, and your home weighing after, with their scales never mixed into your series.
Read the Vacation Stretch as One Story
Compare the return entry with the pre-trip anchor, and read the carer's notes alongside the figures. A small shift backed by notes about refused meals tells a different story from the same shift alongside notes about extra portions from a generous feeder, and the two stories call for different responses at home.
If the direction surprises you, or keeps moving in the days after she is home and eating normally again, take the list to her vet rather than setting any goal figure yourself. A healthy weight for her is a vet judgment made with her body condition in hand. Her vacation-anchored list rests inside Pet Passport with the method written at its head, and KinsLe preserves that series intact for the next trip away.
