Proof persuades a cattery when it can be checked in seconds at booking or drop-off, not when it has to be reconstructed from texts, bank statements and memory in the car park. One dedicated page for her prevention, written up at the moment each treatment happens, turns a stressful question into a page you can simply hand over or send as a photograph.
The Prevention Page and Its Three Fields
Give the page exactly three fields for every entry, and use the same three every time: product, date given, next due date. Product means what was actually used, written as its general kind, for example flea prevention tablets or a worming treatment, rather than a nickname only you understand. Date given is the day the treatment was administered, entered that same day. Next due date is taken faithfully from what the vet noted, or from what the directions printed for that specific treatment state; the page records the interval that applies to her treatment, it does not invent a schedule of its own, and where a vet has set her timing, the vet's date is the one written down.
A worked entry, copied in the same three fields, reads like this. Product: flea prevention tablets. Date given: 6 May. Next due date: 3 June, as stated in the vet's note for that treatment. Every entry on the page, flea or worming, follows that identical pattern, so a cattery reader can scan down the columns and confirm that the current treatment of each kind is still within its recorded dates.
Packaging, Photographs and the Calendar
Hold onto the pack, or the receipt, for whichever treatment is currently in force until its replacement arrives, because the physical pack backs up the page with the batch and product details your handwriting might shorten. Take a photograph of the page alongside the current packaging as a backup, stored with her other records, so a lost folder never means lost proof and a cattery that asks in advance can be sent the photograph the same day. Put the next due date into your calendar at the moment you give each treatment, with a reminder a few days ahead, since prevention lapses quietly in busy months and a cattery spotting an overdue date at drop-off leaves you with a cat, a suitcase and a problem.
Keeping Flea and Worming Entries From Masking Each Other
Track the two kinds of treatment as separate lines of entries on the same page, flea entries in their own run and worming entries in theirs, because a page read quickly can hide an overdue worming treatment behind a very current flea one. Before you book any stay, read down both runs and check the entry at the head of each run against its own next due date, not against the other treatment's. If a cattery asks only about one kind, answer from the page, not from a general feeling that everything is current, and send a photograph of both runs in advance.
When an Entry Is Missing, and Agreeing Proof in Advance
Gaps happen. Never fill a gap from memory or by guessing an interval backwards, because a confident wrong date is worse proof than an honest gap. Ask the vet who supplied or administered the treatment to confirm what their own clinical record shows, and enter the confirmed details with a note that they came from the practice. If a due date genuinely cannot be recovered, tell the cattery plainly and ask what it wants to do; facilities deal with honest owners far more easily at booking than with surprises at drop-off.
Before a first stay, ask the cattery what it accepts as proof and get its agreed terms confirmed in writing, including how current each treatment must be at the stay dates and what happens to the booking if paperwork falls short, because facilities set their own rules and a written answer prevents a dispute at the door. Pet Passport, held inside KinsLe as her records packet, stores a photographed copy of that prevention page beside vaccination paperwork for boarding checks.
