🐾 The First Week Home With a New Pet

Set up a safe space, keep the first days calm, book the first vet visit and build routines that help a new dog, cat or small pet settle in.

Before arrival: prepare a safe base

Before your new companion arrives, choose one area as their base camp. For a dog, that might be a crate or a gated corner; for a cat, a quiet spare room or bedroom works well. Giving the whole house on day one can overwhelm an animal that doesn't yet know where anything is.

• Dogs: a crate or bed, water bowl, house-training supplies, and a couple of safe chew toys
• Cats: a hiding box or covered bed, litter box, scratching post, and food and water placed well away from the litter
• Small mammals and reptiles: an enclosure set up several days in advance so temperature and humidity are already stable

Walk through your home at pet height. Tuck away electrical cords, small objects, toxic plants and anything breakable. Check window screens and block gaps behind appliances and furniture; frightened cats and small animals can squeeze into astonishingly tight spaces, and retrieving them from behind a washing machine is no one's idea of a welcome.

Day one: quiet and simple

Save the welcome party for later. When you get home, place the carrier in the base area, open the door and let the animal come out in its own time. Pulling a nervous pet out, or having the whole family crowd around, only raises stress.

It's common for a new pet to skip a meal or hide for hours. Feeding the same food they had before reduces the chance of an upset stomach on top of everything else. Take a new dog straight to the spot you want them to use as a toilet so they can sniff it first. Show a cat where the litter box is, then give them space. If children live in the house, practice beforehand: sitting quietly on the floor and letting the animal approach is the best way to make a friend.

Days two to four: build a predictable routine

Animals feel secure when life is predictable. Keep mealtimes, walks, play sessions and bedtime at roughly the same times every day. Puppies and newly adopted dogs usually need to relieve themselves after waking, eating and playing, so take them out at those moments and reward success immediately with praise or a small treat.

Start short practice absences now. If you spend the first week glued to your new dog and then leave for a nine-hour workday, the contrast can trigger separation distress. Step out of the room for a few minutes, come back calmly, and gradually extend the time.

Once a cat is eating, using the litter box and grooming normally in their room, you can open the door and let them explore the rest of the home at their own pace. For hamsters, rabbits and other small mammals, resist handling for the first few days. Sit near the enclosure, talk softly and offer treats through the bars or by hand so they learn your voice and scent.

The first vet visit

Book a checkup within the first few days, even if your new pet seems perfectly healthy. Animals from shelters, pet shops or other homes can carry parasites or infections that aren't obvious yet, and an early exam gives your vet a healthy baseline to compare against later. If you have other pets, waiting for the all-clear before introducing them is sensible.

Bring every document you received: vaccination and deworming history, spay or neuter records, the name of the food they've been eating, and a fresh stool sample if the clinic asks for one.

• A physical exam covering weight, temperature, heart and lungs, ears, eyes, teeth and skin
• A vaccination and parasite-prevention plan tailored to age and lifestyle
• Advice on spay or neuter timing, microchipping and local registration
• Portion sizes and treat guidelines

For exotic pets, call ahead to confirm the clinic actually treats that species. Write your questions down beforehand; appointments go by quickly and it's easy to forget something once you're in the exam room.

Introducing resident pets

If another pet already lives with you, go slowly. With cats, keep them in separate rooms for several days and swap blankets or toys so each gets used to the other's scent. Next, let them see each other through a cracked door or baby gate during meals. Only when both stay relaxed should you allow short, supervised time together.

Dogs generally meet best on neutral ground. A parallel walk with loose leashes, where the dogs can sniff the same route without facing off, is a gentler start than a doorway greeting. When introducing a dog to a cat, make sure the cat always has an escape route upward, such as a cat tree or shelf the dog can't reach.

Some small animals should not share space at all. Syrian hamsters are solitary and will fight, and housing rabbits with guinea pigs is discouraged because of differing needs and the risk of injury. Check the social needs of your species before combining anyone.

Health signs to watch during week one

Stress from a move can cause a skipped meal or slightly soft stool for a day or two. Some signs, however, should never be written off as adjustment:

• A dog or cat that eats nothing at all for more than a day, or stops drinking
• Repeated vomiting or diarrhea, or any blood in either
• Persistent coughing, sneezing, nasal or eye discharge combined with lethargy
• A cat straining in the litter box while producing little or no urine, which is an emergency
• A rabbit or guinea pig that stops eating or passing droppings for more than half a day

Young animals and small species can decline quickly, so err on the side of calling. A simple daily log of food eaten, toilet habits and energy level takes a minute and makes small changes easy to spot. It also gives your vet accurate information instead of guesses.

Give it time

Don't judge the relationship by the first week. Some animals settle onto the sofa within a day; others spend weeks under the bed before they trust anyone. Your job is to provide safety, consistency and patience while they work it out. New routines can tire owners too, so share tasks within the household and reach out to your vet, shelter or breeder whenever you hit a problem. Small steps forward are the whole point.
