Hamsters & Mice

Hamsters and mice are popular small pets known for their playful personalities and ease of care. Though tiny, they have specific needs to thrive and live healthy, happy lives. This guide covers everything from setting up the perfect habitat to feeding and health maintenance.

Housing & Environment

Cage size: Provide at least 450 sq. inches of floor space for hamsters; mice cages can be slightly smaller but must offer plenty of vertical and horizontal space for climbing and exploring.

  • Bedding: Use dust-free, absorbent materials such as paper-based bedding or aspen shavings (avoid cedar/pine for respiratory safety).
  • Hideouts: Offer tunnels, nesting boxes, and tubes for burrowing and shelter.
  • Cleaning: Spot clean daily, fully clean the cage weekly to prevent odors and bacteria build-up.

Feeding Your Hamster & Mouse

  • Diet basics: Commercially formulated pellets or blocks designed for hamsters/mice provide balanced nutrition.
  • Fresh foods: Supplement with small amounts of fresh vegetables (carrots, broccoli, cucumber) and occasional fruits (apple slices, berries). Avoid citrus and sugary treats.
  • Water: Provide clean, fresh water daily in a sipper bottle.
  • Chewing: Offer safe chew toys or untreated wood blocks to maintain healthy teeth.

Behavior & Enrichment

  • Hamsters are mostly solitary; house them separately to avoid fighting (except dwarf hamsters, which sometimes tolerate cage mates).
  • Mice are social and thrive in small same-sex groups.
  • Both species enjoy exercise wheels, tunnels, climbing toys, and foraging activities to prevent boredom.
  • Handle gently and regularly to build trust and reduce stress.

Health & Signs to Watch For

  • Monitor for signs of illness: weight loss, lethargy, rough fur, sneezing, or discharge.
  • Dental health is crucial; overgrown teeth can cause eating problems.
  • Regularly trim nails if they get too long.
  • Consult an exotic pet vet for any health concerns.

Quick Tips for New Owners

✔ Avoid direct sunlight and drafts in cage placement
✔ Maintain a consistent feeding and cleaning schedule
✔ Never pick up by the tail—always scoop gently from below
✔ Provide a quiet environment for restful sleep (hamsters are nocturnal)
✔ Avoid sudden loud noises or rapid movements to reduce stress
