Mice are a rodent animal. They can make ideal pets due to their small size, ease of care & quiet nature.

They can be very interactive & sociable animals who readily accept human companionship. They can become very used to handling, especially if handling is started at a young age. Mice can come in a variety of coat colours & coat lengths.


  • Mice can be housed in a range of cage types. Provide a cage as large as possible and ensure that it is easy
  • to clean & well ventilated
  • Ensure that the area that they’re kept in will not become too hot as they are prone to heat stress
  • Regularly clean the cage & change their bedding to avoid ammonia build up
  • Suitable bedding materials include shredded newspaper or pelleted recycled paper ‘cat-litter’. Mice love to burrow, so make sure a good thickness of bedding is provided
  • Make certain that the cage is predator proof
  • Provide overturned boxes for ‘hiding’ places
  • Use dripper type water bottles. Water bowls are likely to become soiled
  • Mice are sociable animals, consider housing at least 2 together (paired females tend to get on better than paired males). They can also be housed in colonies.


  • Mice can usually be handled quite easily. Pick them up by gently placing your hand(s) under them & be sure to support the full length of their body
  • They can also be gently picked up from the base of their tails
  • Encourage daily handling & play/explore time outside of their cage but beware their ability to scurry away!
  • Mice should be provided with daily exercise & mental stimulation to avert obesity & boredom
  • Be sure to wash your hands after handling your mice


  • Mice are omnivores (they eat plant & animal material). They will eat a wide variety of food if offered
  • Mice can be offered small amounts of good quality mouse/rat pellets (ensure they have a protein content of at least 16% & fat content of 4-5%) & ad lib fresh fruits & vegetables daily. Some examples of these include; Fruit & Vegies: apples, pears, banana, melons, stone fruits, citrus fruits, broccoli, cabbage, brussel sprouts, endive, carrots, Bok Choy/other Asian greens, celery, parsley, berries, tomato, fresh corn, beans, peas
  • Avoid feeding mice a seed/grain mix. Mice are very prone to becoming obese & malnourished on these mixes. They tend to ‘select’ their favourite bits in the mix
  • Treats (should only be offered in very small amounts!) Cereals, grains, seeds, breads, biscuits, sweets, cooked pasta & rice, breakfast cereals, chocolate!

Health and Veterinary Care

  • Have any newly acquired pet mouse checked by a vet, especially if you intend to mix the mouse with others. Thereafter have them checked at least annually
  • At home you should always monitor closely your mice food intake, body condition, eyes, ears, mouth, feet & toileting behaviour
