Short answer

Start with a meet-and-greet so your cat and sitter meet while you are home. Then stock and label food, litter and medication, show the sitter your cat's hiding spots, leave the carrier out, and remove lilies and other hazards. Write down your vet's details and agree on what gets a call right away, such as a cat that stops eating or strains in the litter box, which Cornell says can be an emergency.

Start with a meet-and-greet

You have a trip coming up and a cat who hides when the doorbell rings. The easiest first step is letting the sitter meet your cat, and your home, while you are there. Every new client with us schedules a meet-and-greet using our client forms, and the Petsitting Form there asks for your contact details, your cat's description, medical condition and favorite toys, your vet's name and contact details, special instructions, and your consent to give treats and to take your cat to your vet in an emergency.

Many cat sitters also suggest a short trial visit before a long trip, so your cat sees the same person a second time and you can answer questions about anything that came up. Plan both early, since many sitters' holiday schedules fill up well ahead.

Stock supplies and label everything

Set everything out in one spot so the sitter doesn't have to search your cabinets. A clear setup also means each visit can go to your cat, not to hunting for the scooper.

  • Food for the whole trip, plus extra in case your return is delayed, with portions and feeding times written down. Cornell notes that changes in food can bring back bladder flare-ups in some cats, so stick with what your cat already eats.
  • Litter and bags. Cornell suggests one more litter box than the number of cats. The ASPCA advises against ammonia, deodorants and scents, especially lemon, when cleaning the box.
  • Water bowls in more than one place, away from food and litter, which the AAFP's owner tips recommend.
  • Medication in its original packaging, with your vet's written instructions and what to do if a dose is missed (ask your vet).
  • Cleaning supplies for accidents or hairballs, and paper towels.
  • The carrier, out and open, plus a towel to drape over it.

Show the sitter where your cat hides

A shy cat may spend the first visits under the bed. That's normal, and it's why the sitter needs to know where to look. The AAFP's tips for owners say every cat needs a safe place to retreat to, such as a cardboard box, a carrier or a raised perch, and that people should let the cat choose and control contact.

Walk the sitter through your cat's usual spots, including the odd ones: the back of the closet, inside the box spring, behind the washer. A careful sitter usually tries to see your cat at every visit without dragging it out. Leaving the carrier out as one of those safe places can make it familiar, and it is ready if your cat ever needs a trip to the vet.

Cat-proof doors, windows and plants

Tell the sitter if your cat dashes for the door, and ask them to check window screens and close off rooms you don't use. The ASPCA recommends keeping cats indoors, so make sure everyone who comes in knows to keep your cat inside.

Lilies need their own warning. The FDA says every part of a true lily or daylily is toxic to cats, including the pollen and even the water in the vase. A small bite, a few grains of pollen licked off fur, or a drink from the vase can cause fatal kidney failure in less than 3 days, and the FDA says treatment delayed by 18 hours or more generally leads to kidney failure that can't be reversed. Take bouquets out of the house before you go, and check gifts that arrive while you are away. Cornell's common cat hazards page adds human medications and household cleaners to the list. Our guide to foods and plants toxic to dogs and cats has more.

Agree on what gets a phone call

Cats often don't show obvious signs of pain or sickness, the AAFP notes, so small changes matter. Agree with your sitter on what they should report right away and how to reach you. The table below covers the signs that can't wait, based on Cornell and FDA guidance. Our guide on how long a cat can be left alone explains why. Before you leave, settle these details:

  • Your phone number, and a backup person nearby who has a key.
  • Whether you want an update after every visit or only when something changes.
  • Who can make a decision about vet care if you are on a plane or out of signal.
  • Which signs mean the sitter should call your vet first and you second.
Signs your cat sitter should report right away
What the sitter seesWhy it mattersWhat to do
Food left uneaten, or much less eaten than usualCornell says loss of appetite can seriously affect an adult cat within 24 hoursThe sitter calls you during that visit, then your vet
Straining in the box, frequent trips, little or no urineCornell calls a urinary blockage a true medical emergency, especially in male catsCall your vet or an emergency clinic right away
Any sign the cat chewed a lily, its pollen or vase waterThe FDA says lilies can cause fatal kidney failure, and early treatment mattersCall your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 (a consultation fee may apply)
Spilled pills or chewed medication or cleaner bottlesCornell warns human medications and household cleaners can poison catsCall your vet or ASPCA Animal Poison Control
Lethargy, weakness or poor appetiteCornell lists these among signs of dehydrationThe sitter calls you and your vet
Hiding more than usual but eating and using the boxThis may be shyness, but the AAFP notes cats often don't show obvious signs of sicknessNote it in the visit update and keep checking food and litter

Write the vet plan down

Put your vet's name, phone number and address on the counter or fridge, plus the nearest emergency clinic you would want used after hours. Decide in writing what the sitter may approve if you can't be reached. Our pet emergency plan guide walks through those choices.

If your cat has a health condition, ask your vet which changes would worry them, and add those to the sitter's list. For medication, write the dose and timing exactly as your vet prescribed. Our cat sitting visits can give pills, liquid medication or medication mixed into food, and our cat feeding visits can handle special diets. To see what a visit looks like step by step, read what a professional pet sitter actually does during a visit.

When a sitter isn't the right plan

If your cat is recovering from surgery, needs injections, or needs to be watched closely for a medical problem, ask your vet whether boarding at the clinic would be safer. Our guide to cat sitting vs. boarding compares the two, and our guide to cat sitters vs. automatic feeders covers short gaps.

For most healthy cats, staying home with visits keeps the routine steady. You can read how visits work in our posts on cat sitting in Mount Rainier and cat sitting in Edgewood and Brookland.

When to call a vet

Your sitter should call your vet right away if your cat strains in the litter box and passes little or no urine, which Cornell calls a true medical emergency, or if your cat stops eating. If your cat may have eaten any part of a lily, a medication or a household chemical, call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 (a consultation fee may apply). Bring the plant or the label if you can, as the FDA and Cornell suggest.

Frequently asked questions

How do I get my cat used to a new cat sitter?
Have the sitter meet your cat while you are home, and let your cat set the pace. The AAFP says to let cats choose and control contact, so the sitter should not force petting or pull your cat out of hiding. A second short visit before your trip can help. Leave favorite toys and treats where the sitter can use them, if you have given consent for treats.
What should I leave out for my cat sitter?
Food for the whole trip plus extra, written portions and feeding times, litter and bags, clean water bowls, medication with your vet's written instructions, cleaning supplies and the carrier. Add your vet's details, the nearest emergency clinic and how to reach you. Our post on pet sitter instructions has a full checklist for the note itself.
Are lilies really dangerous to cats?
Yes. The FDA says true lilies and daylilies are very dangerous to cats, and every part of the plant is toxic, including pollen and vase water. Eating a small amount can cause fatal kidney failure in less than 3 days. Keep them out of the house, and call your vet or ASPCA Animal Poison Control right away if your cat may have touched one.
Should I leave my cat's carrier out?
It can help. The AAFP lists a cat carrier as one example of a safe place where a cat can retreat. A carrier your cat already knows is less scary, and it is ready if your sitter has to take your cat to the vet in an emergency. Show the sitter where it is, and tell them how your cat usually goes in.
Can a cat sitter give my cat medication?
Many cat sitters can give oral medication, and our visits include pills, liquid medication or medication mixed into food. Leave the medication in its original packaging with your vet's written dose and timing, and ask your vet what to do if a dose is missed. If your cat needs injections or close medical monitoring, ask your vet whether boarding at the clinic is safer.
