Keep Her Setup Exactly as Her Owner Left It
A cat in temporary care is already adjusting to a missing person, so stability is your best cleaning tool. Leave the litter box in the same room, facing the same way, filled to the same depth with the same kind of litter her owner used, even if you would arrange your own home differently. Moving the box or switching litter to chase a fresher smell often backfires: a unsettled cat may avoid an unfamiliar box and toilet on bedding or carpet instead, which creates far worse odor and mess. If the box must move because of your household layout, shift it a short distance at a time over several days and keep the old spot clean and unobstructed until she is confidently using the new one.
A Twice-Daily Rhythm You Can Sustain for Months
Deployment care can last a long while, so build a routine you will not abandon by week three. Scoop morning and evening, remove the bag from the house the same day, and set one fixed weekday for the fuller tasks: washing the box, laundering the mat under it, and vacuuming the soft furnishings where she sleeps. Brush her in short, calm sessions where she already relaxes — many cats accept a few strokes on the sofa far better than being carried to a grooming spot — and lift loose fur from her favorite chair with a damp hand or lint roller as part of that same weekly round. Little and predictable beats an occasional intensive blitz that stresses both of you.
Protect Shared Rooms Without Shutting Her Out
It is tempting to close doors to keep hair out of bedrooms and off the good sofa, but shutting a temporarily homed cat out of most of the house shrinks her world at the moment she most needs normalcy. Instead, cover her chosen resting places with washable throws you can launder weekly, keep a mat at the litter box exit to catch tracked granules, and sweep the route between box, food and her main sleeping spot every day or two. If she is shedding heavily with the season or with stress, a brief daily brush will visibly reduce what lands on furniture within a week.
Write It Down for the Person Who Is Away
Keep a simple running note: dates the box was deep-cleaned, any days she ate less, vomited, hid more than usual, or missed the box, and when fleas or worms were treated if that is part of her care. Photograph the note or keep it with her records so you can hand the owner a truthful picture on return and a veterinarian a useful timeline if she becomes unwell. Do not make permanent decisions — new litter systems, rehoming her favorite chair, changing her food to reduce stool odor — without checking with the owner where contact allows.
Smells and Misses That Need a Vet, Not More Cleaning
A sudden strong ammonia smell despite regular scooping, repeated toileting outside the box, straining, crying when urinating, blood in urine or stool, or a cat who stops eating and hides for more than a day should not be managed with stronger cleaning products. Rule out a dirty or moved box and a household disruption first, then contact her veterinarian and let the owner know through whatever channel you have agreed. Sharing the owner's routine through KinsLe with a Care Pass keeps her litter, brushing and vet information in front of you at each clean, so temporary care still feels like her care.
