Bringing Your Small Pet Home: The First Week
🤎 The short version: the move is stressful for a small pet, so the first week is about settling, not showing off your new friend. Set the enclosure up (and prove any heating holds) before they arrive, let them settle before much handling, keep their existing food and change it only gradually, learn their normal (appetite, droppings, energy), and find an exotic vet now. Get the first week calm and steady, and the bond comes on its own.
This guide is the shared arc across every species — for the exact specifics, always check your animal’s full care guide. The details differ (a hedgehog’s heating, a guinea pig’s vitamin C, a gerbil’s clan), but the settling-in rhythm is the same.
Before they arrive
Set up and check the enclosure completely first. That means the right size and floor, safe bedding at the right depth, hides, water and food in place — and for warmth-dependent species (hedgehog, sugar glider), prove the thermostatically-controlled heating holds a steady range before the animal comes home. For social species, have the grouping sorted and enough resources (hides, bowls, water) for everyone, plus one.
Day 1–2: let them settle
Resist the urge to handle. Let a new pet settle into its space, get used to your presence and voice, and approach you. Sit nearby, talk quietly, and offer food from an open hand rather than reaching in and grabbing. This is how a nervous prey animal learns you’re safe.
Handle at the right time of day, too: nocturnal species (hamster, chinchilla, hedgehog, sugar glider) should be met in the evening when they’re naturally awake — never dig a sleeping animal out of its nest.
The first weeks: keep it steady
- Keep the diet the same at first, then transition gradually to the diet you want to feed. Sudden changes cause dangerous gut upset in grazers especially.
- Learn their normal — how much they eat and drink, what their droppings look like, their usual energy. This baseline is what lets you catch problems early, because small pets hide illness.
- Handle gently and build up supervised out-of-cage time in a pet-proofed space for the species that need it.
- Watch social introductions closely. If you’re bonding a second animal, go slow on neutral territory; watch new groups (especially male rodents and gerbil clans) for aggression.
Find your vet now
Line up an exotic vet that treats your species in the first week. Many common antibiotics are dangerous to rabbits, guinea pigs and hamsters, and small animals decline fast — so you want a vet before you need one. If you’re not sure your new pet is healthy, a first check-up is never wasted.
The honest takeaway
A calm, boring first week is a good first week. Set things up right, let them settle, keep the diet steady, learn their normal, and get your vet sorted — and you’ve prevented most of the early problems new keepers hit. Then browse the full species guides and our free tools to go deeper.

Common questions
How long does it take a small pet to settle into a new home?
Usually a few days to a couple of weeks, depending on the species and individual. The move is stressful — a new smell, a new space, no familiar territory — so the kindest first step is to let them settle before much handling. Win trust with food and calm, low contact rather than chasing or grabbing.
Should I change my new pet’s food straight away?
No. Keep the diet exactly as it was at first, then transition to the diet you want to feed gradually, over days to weeks. A sudden food change can cause serious gut upset, especially in grazers like rabbits, guinea pigs and chinchillas.
What should I do first when I bring a small pet home?
Set up and check the enclosure before they arrive (including heating for warmth-dependent species), let them settle quietly, keep their existing food, learn their normal appetite and droppings, and find an exotic vet. For social species, make sure the grouping is right and every animal has its own resources.
Do I need a vet before anything goes wrong?
Yes — find an exotic vet that treats your species now, not during a 2am emergency. Small pets hide illness and decline fast, so knowing where to go before you need it can be the difference that saves them.
