Hamster First-Week Checklist

In short

A hamster's first week is about a complete enclosure ready in advance and lots of quiet settling time before handling. Let your hamster explore and adjust, interact gently during its active evening hours, and watch eating and activity. This page is planning guidance; identify a small-animal veterinarian early and call promptly if anything seems wrong.

Settle in gently

  • Have the full enclosure — bedding, wheel, hides, food, water — ready before your hamster arrives.
  • Give your hamster several quiet days to settle before much handling.
  • Interact during active evening hours; avoid disturbing daytime sleep.
  • Build handling up slowly, letting your hamster get used to your scent and voice.
  • Watch eating, drinking, and activity, and keep the area calm.

First-week checklist

  • Complete enclosure set up before arrival.
  • Several quiet settling days before much handling.
  • Interaction during active evening hours only.
  • Gentle, gradual handling building trust.
  • Monitoring of eating, drinking, and activity.
  • A small-animal/exotic veterinarian identified early.

What not to assume

  • Do not assume a new hamster wants handling immediately — give it quiet time first.
  • Do not wake a sleeping hamster to play; respect its night-time routine.
  • Do not assume any vet sees hamsters — line one up in advance.
  • Do not ignore reduced eating or a wet rear — contact a vet promptly.

When to contact a veterinarian

Hamsters are small and can decline quickly, and they hide illness. Do not use this page to diagnose — know a small-animal/exotic veterinarian in advance.

  • Not eating or drinking, or sudden weight loss.
  • Diarrhoea or a wet, soiled rear end — a serious sign that needs prompt veterinary care.
  • Laboured breathing, wheezing, or discharge from the eyes or nose.
  • Lethargy, collapse, injury, or suspected poisoning.
  • Any rapid change — hamsters are small and decline quickly, so call promptly.

Hamster First-Week Checklist — Frequently Asked Questions

How do I help a new hamster settle in?
Set up the complete enclosure before arrival and give your hamster several quiet days before much handling. Interact gently during its active evening hours and let it get used to your scent and voice.
When can I start handling my new hamster?
After it has had quiet time to settle — usually a few days — start short, gentle sessions during active evening hours, building trust gradually. Let your hamster come to you rather than grabbing it.
Should a new hamster see a vet?
Identify a small-animal or exotic veterinarian early. Go promptly if anything seems wrong — reduced eating, a wet rear, or breathing trouble all warrant prompt veterinary attention.
