Your Rescue Cat's First Week

Your new cat is under the bed and has not eaten since you got home. That is normal, and it is not a sign you chose wrong. Settling runs roughly three days, three weeks, three months, and almost everything that goes wrong in week one comes from moving too fast. Here is the setup that works, the food and litter rules, and the short list of symptoms that mean a vet tonight.

The short answer

Set up one quiet room with a litter box, food and water apart from each other, two hiding spots and the carrier left open. Use the same food and the same litter the shelter used and change neither this week. Let the cat hide and emerge on its own, usually overnight at first. Register with a Cochrane vet within a fortnight. Go immediately if a male cat strains in the box without producing urine, which is an hours-not-days emergency.

The first week is the part nobody warns adopters about properly. You spend weeks choosing a cat, you get it home, and it disappears behind the dryer for three days. It is easy to read that as rejection, or as evidence that something is wrong with the cat.

It is neither. A cat that has just moved has lost every familiar smell and sound at once. Hiding is what a sensible animal does in that situation, and the cats that hide hardest often turn into the most affectionate ones once they decide the place is safe.

What you control is the environment and the pace. Here is how to set up both.

What to Have Ready Before Pickup

ItemWhy it matters
The same litter the shelter usedA new box and a new substrate in the same week causes accidents
The same food the shelter was feedingDiet change plus stress equals diarrhoea, nearly every time
Two hiding spots in the safe roomA cat that can hide comes out sooner than one that cannot
Water bowl away from the foodMost cats dislike drinking beside their food
Scratching post, tall if possibleDecide where scratching happens before the cat decides
A wand toyPlay is how a frightened cat starts trusting a room
Hard-sided carrier, left open in the roomTurns the carrier into furniture instead of a vet-visit trigger

A full first-year budget for all of this is in our Cochrane cat cost guide.

Three Days, Three Weeks, Three Months

WhenWhat you will seeWhat you should do
Days 1 to 3Hiding, minimal eating, litter use overnight onlyLeave the cat alone. Sit in the room reading, say nothing, expect nothing.
Week 1 to 3Coming out when you are still, testing the room, first playOpen the rest of the house one room at a time. Keep the safe room available.
Month 1 to 3Real personality appears, routines form, lap use may beginFull house access, normal life, first vet visit completed.

The timeline is a guide, not a schedule. Cats that came from rural surrender situations or from colonies frequently take longer, and that is fine. What matters is direction of travel rather than pace.

Getting Home in One Piece

Use a hard-sided carrier, not a cardboard box and not a cat in someone's arms. The shelter is on Griffin Industrial Point and most Cochrane adopters have a short drive home, but a startled cat loose in a moving vehicle on Highway 1A is a genuinely dangerous situation for everybody in it.

Take the carrier straight into the safe room, close the door, open the carrier and then leave. Do not tip the cat out and do not stand over it waiting. Most cats will not come out while you are watching, and that is the correct instinct on their part.

Registering With a Cochrane Vet

Book a first appointment within a week or two. The shelter has already done the vaccines, the deworming and the alteration, so this visit is mostly about establishing a relationship with a clinic before you urgently need one.

Cochrane has two established practices in town. Cochrane Animal Clinic is at 3-124 River Avenue on 403-932-5875 and handles small and large animals. Arrowhead Veterinary Centre is at 118 2nd Avenue West on 403-932-2370, open weekdays 7:30 to 5:30 and Saturdays 9 to 2. Bring the paperwork the shelter gave you.

Sort the town licence in the same fortnight. Under Animal Bylaw 04/2016 every cat over three months old needs one, and an altered cat is $15 a year. Since your cat came home already altered, that is the tier you fall into.

Symptoms That Mean Go Now

The one every cat owner must know: a male cat straining in the litter box and producing little or nothing may have a urinary blockage. This is life-threatening within hours, not days. Do not wait until morning. Go to a vet.

Also urgent: open-mouth or laboured breathing, repeated vomiting, refusing all food for 24 hours or more, obvious injury, seizures, or a swollen painful abdomen.

After hours in Cochrane: local clinics keep daytime hours. Cochrane Animal Clinic refers small animal emergencies to Western Veterinary Specialist & Emergency Centre, 1802 10 Avenue SW, Calgary, 403-770-1340, open 24 hours. That is a 30 to 40 minute drive on Highway 1A in good conditions and longer in winter. Save the number on day one.

Never give a cat human medication of any kind. Several common household painkillers are toxic to cats even in small amounts. If you are unsure about anything, phone a clinic. It costs nothing to ask.

Keeping the Cat In

A cat in its first fortnight has no sense that your house is home, which makes it a flight risk every time a door opens. That matters more here than in a city. The Bow River corridor runs coyotes through Cochrane nightly, owls hunt the area, and Highway 1A does not slow down. Keep the safe room door shut while people come and go, get everyone checking behind them, and make sure the microchip is registered to your current number. The full picture is in our indoor versus outdoor guide.

Frequently Asked Questions

How long does it take a rescue cat to settle in?

Longer than most people expect, and the rough shape is three days, three weeks, three months. The first three days are usually hiding and very little eating. By three weeks the cat has learned the routine and started testing the space. By three months you are meeting the actual personality, which is often noticeably different from the cat you met at the shelter. Nervous cats and cats that came out of rural or colony situations take longer. A slow start predicts nothing about the outcome.

My new cat is hiding and will not come out. Is that normal?

Completely normal, and it is the most common first-week worry there is. A cat that has just moved has lost every familiar smell, sound and surface at once, so hiding is a sensible response rather than a problem. Leave food, water and a litter box in the room and let the cat emerge on its own schedule, which at first will usually be overnight. Do not drag a cat out from under a bed. That teaches it that hiding does not work and that you are the reason, and it sets you back a week.

What is a safe room and why does it matter?

One closed room, ideally a spare bedroom or a quiet bathroom, holding everything the cat needs for the first few days. Litter box in one corner, food and water well away from it, two hiding options, a scratching post and the carrier left open. A whole house is overwhelming to an animal that does not yet know where anything is or where it could escape to. Restricting the space actually speeds settling up. Open the rest of the house one room at a time once the cat is eating and using the box reliably.

How do I switch my cat to a new food?

Slowly, over seven to ten days, and not during the first week if you can avoid it. Ask the shelter what the cat has been eating and buy that food before pickup. Once the cat has settled, mix a small amount of the new food into the old and increase the proportion gradually. Changing diet abruptly on top of the stress of a move is the standard route to diarrhoea, and a cat with an upset stomach then starts avoiding the litter box, which turns one problem into two.

Should I change the litter type too?

Not at the same time, and preferably not for several weeks. Use whatever litter the shelter or foster used, then change it later in gradual steps if you want to. A cat that dislikes a new substrate under its feet in an unfamiliar house will find somewhere else to go, and once it has chosen a corner of the carpet that habit is hard to undo. The standard is one box per cat plus one spare, scooped daily, kept away from both the food and the busiest part of the house.

When should I take my new cat to a vet in Cochrane?

Within the first week or two, even though the shelter has already done the medical work. The visit is less about medicine than about registering with a clinic so you have a relationship before you need one urgently. Cochrane has two established practices in town, Cochrane Animal Clinic on 403-932-5875 and Arrowhead Veterinary Centre on 403-932-2370. Bring the paperwork the shelter gave you so the vet can see what has been done and when boosters are due. Ask about new client wait times when you phone.

What symptoms mean I should go to a vet immediately?

Go now if a male cat is straining in the litter box and producing little or nothing, because urinary blockage is life-threatening within hours rather than days. Also urgent: open-mouth or laboured breathing, repeated vomiting, refusing all food for 24 hours or more, obvious injury, seizures, or a swollen painful abdomen. Cochrane clinics keep daytime hours, so after hours the referral is Western Veterinary Specialist and Emergency Centre in Calgary on 403-770-1340, open 24 hours. Phoning costs nothing and waiting can cost everything.

Where do I go overnight if something goes wrong?

Into Calgary, and you should know this before you need it rather than at two in the morning. Cochrane Animal Clinic refers after-hours small animal emergencies to Western Veterinary Specialist and Emergency Centre at 1802 10 Avenue SW in Calgary on 403-770-1340, which is open 24 hours every day. That is roughly a 30 to 40 minute drive on Highway 1A in decent conditions, longer in winter weather. Put the number in your phone on day one and drive the route once in daylight.

My cat is not eating. How worried should I be?

A slightly reduced appetite in the first day or two is expected and not alarming. A cat that eats nothing at all for more than about 24 hours needs veterinary attention rather than more patience, because cats develop serious liver problems from not eating far faster than dogs do. Try warming wet food a little to raise the smell, offering it somewhere quiet rather than a busy kitchen, and leaving the room while the cat eats. If nothing has gone in by the end of the first full day, phone the vet.

How do I introduce a rescue cat to my resident cat?

Through a closed door, and more slowly than feels necessary. Keep the new cat in the safe room for at least the first week and feed both cats on either side of that door so each associates the other with something good. Swap bedding between them so they learn each other's scent before ever meeting. Then try brief supervised visual contact, then short supervised time together. Hissing and posturing early on are normal. Sustained fighting means going back a stage rather than pushing forward.

How do I stop my new cat escaping out the front door?

Assume it will try, because a cat that arrived last week has no reason yet to think of your house as home. Keep the safe room door closed while people come and go and get everyone checking behind them as a reflex. A microchip registered to your current phone number is the single most useful precaution, and Cochrane requires a cat licence anyway under Animal Bylaw 04/2016. If the cat does get out, search close to the house at dawn and after dark, looking low and under decks rather than up.

When will my cat start being affectionate?

Whenever it decides to, and pushing accelerates nothing. Some cats climb into a lap on day two. Others take three months and then never leave. The reliable way to speed it up is to be boring and predictable, feed on a schedule, play with a wand toy daily, and let the cat approach you rather than reaching for it. Sitting in the room doing something else entirely works remarkably well. Attention offered rather than demanded is the whole trick with a nervous cat.

Should I adopt two cats at once?

It works better than people assume, especially with a bonded pair or two cats that already know each other. They settle faster because they have each other as a familiar element in an unfamiliar house, and they keep each other busy through a long foothills winter when nobody is spending much time outdoors. Two strangers introduced simultaneously is a harder project. If you want two, ask the shelter which cats they would like to place together rather than picking two unrelated ones yourself.
