Two changes at once: another cat and a baby
Sending your cat for a week to a family home that has its own cat and a newborn baby layers two challenges together. Your cat must cope with a strange house and a strange cat, while the household is already tired, busy, and organised around feeding and sleeping a baby. Preparation therefore starts with lowering expectations: the goal for the week is calm separation and a steady routine, not friendship between the cats or charming photographs beside the cot. Ask honestly whether the family has a spare room your cat can claim, and whether an adult has time each day to feed, clean a tray, and sit with your cat. If either answer is shaky, a different arrangement will serve everyone better.
Setting up a base room that stays your cat's
Choose one quiet room, ideally away from the nursery and the resident cat's favourite sleeping spot, and equip it fully before your cat arrives: litter tray in one corner, food and water well away from the tray, a scratching post, a hiding box with bedding from home, and a perch. Your cat lives in that room at first, with scent swapping as the only contact with the resident cat: rub a soft cloth on each cat's cheeks and place it under the other's food bowl so the new smell arrives paired with something good. Any face-to-face meeting comes later, briefly, through a cracked door or baby gate, and only if both cats are eating normally and showing curiosity rather than fixed staring, growling, or attempts to flee.
Protecting the baby, the cats, and everyone's sleep
Agree firm household rules before the stay. Your cat does not go into the nursery, does not sleep on baby blankets or in the cot, and is fed and litter-trayed outside baby areas so hygiene stays simple for exhausted parents. The resident cat's own routine should change as little as possible, because a resident cat who loses territory to a visitor is the one most likely to spray, guard doors, or redirect frustration. Night-time matters too: a visiting cat who cries at a bedroom door will wake the baby and strain goodwill fast, so plan an evening play session and a small late meal in the base room to encourage settling where the cat is meant to sleep.
What to pack and what to agree in writing
Send the usual food measured for the week, the familiar litter, any care notes in plain language, vaccination proof, microchip details, and the vet's contact information, plus a worn item of your clothing for the base-room bed. Write down what normal looks like for your cat: appetite, tray habits, how hiding shows stress, and which handling the cat dislikes, so the family does not misread a shy cat as a sick one or a sick one as merely shy. Set a low-effort update rhythm the parents can actually keep, such as one photo and one line each evening. If either cat stops eating, fights cause an injury, or your cat strains in the tray or vomits repeatedly, the family should contact a vet promptly instead of waiting out the week.
A handover that respects a newborn household
Do the handover quickly, kindly, and at a time that does not collide with a baby feed, and leave before prolonged goodbyes unsettle your cat. Put the separation rules on the first page of the notes, because a sleep-deprived adult at midnight needs the short version. Through KinsLe Care Pass, the family receives temporary access to the base-room setup, the cat-separation rules, and your cat's daily routine without you sending scattered messages through the week.
