For a shy cat, a first cattery stay is not a social event to be enjoyed. It is an unfamiliar place to be endured as quietly as possible, and every choice you make should lower the amount of novelty, noise and handling she has to absorb.
Choose a Pen That Lets Her Retreat
Visit the cattery before booking and look at it through her eyes. Ask for a quiet pen requested in advance, away from dog boarding, reception noise and busy walkways, and ask what the pen contains: she needs a hiding option inside the pen, such as a covered bed, a box or a high enclosed shelf, where she can be out of sight of passing people and neighbouring cats.
Ask how staff approach shy cats, how often pens are entered, whether she can be fed and cleaned around with minimal handling, and whether updates cover the night, when shy cats often eat, use the tray and explore. Tell them honestly that she hides and how she prefers to be approached: slowly, from the side, with no reaching into her hiding place to pull her out. Staff who hear that as useful information, rather than fuss, are the staff you want.
Because a cattery is a paid service, get the provider's agreed terms confirmed in writing before the stay: the trial terms, the overnight arrangements and the rates, plus what happens if you need to collect her early.
Pack Her Home Scent Without Washing It Away
Send familiar scent with her in several forms, because smell is the continuity she will actually notice. In the days before the stay, let her sleep on the bedding that will travel, and add a worn item of your clothing that you have kept unwashed since wearing it, placed near her bedding rather than freshly laundered. Pack her usual food for the whole stay plus a spare day, measured and labelled by meal, so there is no sudden diet change on top of a new place, and tell staff not to substitute treats or a different food if she is slow to eat on the first night without contacting you.
Include a note of her normal pattern: when she eats, where she likes a tray, the words and sounds she knows, and the signs that she is overwhelmed, such as staying in hiding through the night as well as the day or leaving food untouched. Ask the cattery to keep her bedding and clothing item with her unwashed; their smell is the point of them.
Use a Trial Night and Brief Staff on Quiet Handling
Book a trial night first if the cattery offers one, and treat it as information for both of you. A single night tells you whether she eats, uses the tray and settles after lights-out in that environment, and it teaches her that this strange place is somewhere she leaves again, which makes a longer stay less absolute. Collect her calmly, ask for an honest account covering the night hours, and adjust the main booking if the trial shows she needs a quieter pen or a sitter at home instead.
Brief staff that good handling for her means very little handling: no carrying her around to meet people, no lifting her out for a fuss, and no attempts to socialise her with neighbouring cats. Shy cats cope by retreating, and a pen she can withdraw into, checked by a familiar routine of quiet visits, respects how she actually manages. Ask staff to let her eat and use the tray unobserved, to speak before entering her pen so she is not startled, and to call you if she has not eaten across a full day and night.
On collection, bring her straight home to a quiet room with her own tray, water and bedding, and let her reappear in her own time rather than unpacking her into a busy household welcome. Her pen carer can check the same brief through Care Pass on KinsLe, where access is time-boxed to the trial and main stay you booked.
