Start with the routine only you know
A senior cat depends on sameness more than a younger cat does, and much of what keeps her calm lives only in your head. Write out her day as it actually happens: when she eats and how much, which food she accepts and which she leaves, where her litter boxes sit, how she signals she wants company, and the chair or windowsill she claims in the morning. Note the details a substitute would miss — that she drinks more readily from the bowl by the kitchen door, that she dislikes being lifted, that she hides under the bed when the doorbell rings. This written routine is the core of any backup plan, because it lets another person reproduce her normal day rather than improvising one.
Choose helpers before you need them
Pick one person who could realistically come daily — a family member, neighbour, or trusted sitter — and a second person as backup if the first is away. Invite each of them over while you are well and walk the house together: show them where food is stored, how the litter is scooped, how your cat prefers to be approached, and which doors must stay closed. Talk honestly about scenarios: a few days when you cannot manage stairs, a hospital stay, or a permanent change where bending and lifting become hard. Agree in advance who feeds, who cleans boxes, who can take her to the vet, and how you will stay in touch about her.
Make the house easier for both of you
If your mobility is already changing, small rearrangements help you and any helper. Move food, water, and one litter box to the floor you spend most time on so neither of you must carry supplies up and down stairs daily. Keep a week's food and litter within easy reach rather than in a basement or high cupboard. A low-sided litter box serves your cat's stiff joints and is also simpler for a helper to clean. Put night lights along the route to her box and bowl so evening checks are safer for a person with unsteady footing as well as for an older cat whose vision may be fading.
Keep her health information ready to hand over
Gather her vaccination record, recent vet summaries, and a list of any ongoing conditions your vet is monitoring, together with the clinic's phone number and your instructions for emergencies. Write down what her normal looks like — appetite, weight trend, how high she still jumps, how she sleeps — because a helper who knows her baseline will notice a change sooner. If you are ever unable to explain things yourself, this packet speaks for you, and a vet seeing her for the first time gets her history in minutes rather than piecing it together from memory.
Review the plan as she ages
A plan made when she was still jumping to the counter may not fit a cat who now needs steps, softer food, or help reaching a warm sleeping spot. Revisit the written routine whenever her habits shift, after each vet check, and whenever your own situation changes. Update the helpers too, so nobody is working from an old version that lists a food she no longer eats or a room she no longer uses. Planning is not a single document; it is a habit of keeping her information current while you are able to do it thoughtfully.
With her routine, contacts, and health history gathered in a KinsLe Pet Passport, the people you trust can step in smoothly and your senior cat keeps the familiar care she relies on.
