What Does a Cat Sitter Do? Duties, Visits, and Limits Explained

A cat sitter comes to your home to care for your cat while you are away. On each visit they feed your cat, refresh the water, scoop and clean the litter box, give any prescribed medications, and spend time on play and companionship. They also monitor your cat's health, handle light home tasks, and send you a photo update after every visit.

If you are weighing your options before you travel, it helps to understand exactly what is included and what is not. This guide breaks down the core duties, the health checks a good sitter runs, and the difference between a quick drop-in and an overnight stay. For the wider picture of how in-home care works, start with our pet sitting hub, then come back here for the cat-specific detail.

The core duties on every cat-sitting visit

Pet Sitters International, the leading trade body for the profession, lists the standard visit tasks as feeding, changing the water, cleaning litter boxes and any messes, administering medication if needed, providing play and exercise, and giving plenty of attention (Pet Sitters International). For a cat, that translates into a predictable routine on each stop.

Feeding and fresh water. The sitter measures out food to your written instructions, whether that is wet food, dry, or a mix, and refreshes the water bowl or tops up the fountain. Cats are sensitive to stale or low water, so a sitter should empty, rinse, and refill the bowl rather than just adding more on top.

Litter scooping and cleaning. A clean box is one of the biggest reasons cats stay relaxed and keep using the litter tray. The sitter scoops solids and clumps every visit, wipes spills, and tops up litter as needed. If you have multiple cats, expect the sitter to service each box. The general rule of thumb is one box per cat plus one spare, which we cover in how many litter boxes per cat.

Medication administration. Many sitters give oral, topical, and some injectable medications when you provide clear instructions. Pilling a cat is a genuine skill: Cornell's veterinary pharmacy advises staying calm, prepping the dose in advance, and following an oral pill with a small amount of water so it does not lodge in the esophagus (Cornell Feline Health Center). Leave written dosing, timing, and a photo of the medication so nothing is guessed.

Play, companionship, and grooming. Beyond the chores, a good sitter spends time with your cat: wand-toy play, gentle brushing if your cat enjoys it, and simple company so a social cat is not alone for a full day. Shy cats may just want a calm presence in the room. The sitter follows your cat's temperament rather than forcing interaction. Brushing is more than cosmetic for many cats. Regular strokes with a comb reduce hairballs, spread skin oils, and give the sitter a chance to feel for lumps, mats, or fleas that a quick glance would miss. For a long-haired cat left alone for a week, a few minutes of grooming per visit keeps the coat from matting into painful knots.

Every one of these tasks runs off your written instructions, so the more detail you leave, the closer the care matches your normal routine. Note food amounts and brands, feeding times, where the litter and cleaning supplies live, your cat's hiding spots, and any words or sounds that reassure a nervous cat. A sitter cannot follow a routine they were never told about, and cats notice the difference when their schedule slips.

Health monitoring: the part owners underrate

A professional sitter is also a second set of eyes on your cat's wellbeing. Cats hide illness well, so the daily check is genuinely useful. On each visit a sitter should note whether food is being eaten, whether the litter box output looks normal, and whether your cat is behaving like itself.

• Appetite. Untouched food across visits is a red flag. A cat that stops eating for more than a day needs a vet, because cats can develop serious liver problems when they go without food.
• Litter box changes. No urine, straining, blood, or a sudden change in stool all matter. A male cat straining and producing nothing can be a life-threatening urinary blockage that needs same-day care.
• Hydration and energy. Sunken eyes, tacky gums, or skin that is slow to spring back can signal dehydration. Hiding, wobbliness, or heavy breathing are all worth flagging.

The ASPCA's general pet care library is a good baseline for the normal-versus-not signs owners and sitters should watch (ASPCA), and Cornell's feline health topics cover appetite, vomiting, diarrhea, and hydration in more depth (Cornell Feline Health Center). A sitter's job is not to diagnose. It is to notice early and escalate, which is why you always leave your vet's number and an emergency plan.

Light home tasks that keep your place safe

Because a sitter is in your home anyway, most will handle small house-care jobs to give the place a lived-in look. Pet Sitters International notes sitters commonly bring in mail and newspapers and alternate blinds and lights so the home does not look empty (Pet Sitters International). Typical home tasks include:

• Bringing in mail, packages, and newspapers
• Watering indoor plants on your schedule
• Rotating a few lights or blinds for a lived-in look
• Taking bins to the curb and back on collection day
• A quick security check for leaks, open windows, or anything out of place

Confirm which of these are included versus extra when you book. Some sitters bundle basic home tasks into the visit fee; others treat heavy plant care or trash duty as add-ons. These small jobs matter for security as much as convenience. A pile of uncollected mail or a fully dark house for a week signals to opportunists that nobody is home, so a sitter who rotates lights and clears the doorstep is quietly protecting your property while they care for your cat. Leave clear notes on which plants need water and how often, since overwatering can do as much damage as neglect.

Updates and photos after each visit

A modern professional sitter closes each visit with a written update and photos: what your cat ate, how the litter looked, mood and energy, any meds given, and a picture or two. This is your proof the visit happened and your early-warning system if something seems off. If a sitter will not commit to per-visit updates, treat that as a gap. When you interview candidates, the update policy is one of the key questions to ask a pet sitter.

Drop-in visit vs overnight stay: what changes

The same core duties apply whether you book quick drop-ins or an overnight sitter, but the coverage and the price differ. A drop-in is a scheduled visit of roughly 20 to 60 minutes, booked once, twice, or three times a day. An overnight sitter stays in your home through the night, so your cat has company for the hours it would otherwise be alone. The table below shows how the two compare across the duties owners care about most.

One thing worth clearing up: the core duties do not shrink on a drop-in. Your cat is still fed on schedule, the litter is still scooped every visit, and medications are still given at the right times. What an overnight adds is presence. Instead of your cat facing an empty house from the last evening visit until the next morning, a sitter is there through the night to notice a problem, offer comfort, and respond fast if something goes wrong. That continuity is the whole reason overnights cost more, since the client has exclusive use of the sitter's time for those hours.

Drop-ins suit a confident adult cat that is content alone between meals. An overnight cat sitting booking makes more sense for kittens, elderly cats, cats on time-sensitive medication, or any cat that gets stressed by long stretches of solitude. If you are still deciding between formats, our comparison of drop-in pet sitting vs overnight lays out the trade-offs, and how much a cat sitter costs breaks down the price gap between the two.

What a cat sitter does NOT do

Setting expectations up front avoids friction later. A cat sitter is a caregiver, not a vet, a housekeeper, or a contractor. In general, a sitter does not:

• Diagnose or treat illness. They monitor and escalate to your vet. They do not perform medical procedures beyond the routine medications you have authorized.
• Deep-clean your home. They tidy pet areas and litter, not scrub bathrooms or do your laundry.
• Run unrelated errands. Grocery runs, dry cleaning, or personal errands are outside a standard cat-sitting scope.
• Board your cat at their place. In-home sitting means care in your home. If you want your cat cared for elsewhere, that is boarding, which we cover in cat boarding vs cat sitting.
• Guarantee constant supervision on drop-ins. Between visits your cat is alone, which is exactly why anxious or medically fragile cats are better suited to overnights.

Anything outside the standard scope is negotiable, but it should be agreed and priced before your trip, not sprung on the sitter mid-week.

How a professional differs from a friend or an app

A professional cat sitter carries insurance and bonding, follows a documented routine, and is trained to spot health problems early. To become a Certified Professional Pet Sitter with Pet Sitters International, a sitter must pass an exam, agree to the association's quality standards and code of ethics, and complete 30 hours of continuing pet-care education every three years (Pet Sitters International). A neighbor doing you a favor rarely offers that. If you are torn between a paid pro and a favor from someone you know, weigh it up in should you hire a cat sitter or ask a friend, and if you are comparing an independent sitter against a booking app, see our take on a professional cat sitter vs an app. Cats also do well with a caregiver who blends care and company, which is the idea behind companion pet sitting.

Whichever route you choose, the fundamentals stay the same: clear written instructions, a vet contact and emergency plan, a working key or entry method, and honest detail about your cat's quirks. Get those right and a good sitter will keep your cat fed, medicated, clean, and calm until you are home.
