The Spiny Mouse is a large stocky mouse. Its name comes from its prickly hairs on its rump. They make good pets and can become very tame. Their lifespan is long which makes them an interesting species to keep and/or breed. One thing to keep in mind when it comes to keeping this mouse is its incredibly delicate tail. This should be considered when it comes to housing and handling. If the tail become snagged or if you attempt to pick up your mouse via its tail it will literally break off.

Housing

  • An aquarium with a mesh lid we find is the best option due to the risk of their tails getting caught between the bars of a cage.
  • We would recommend either keeping single sex groups or a group with a single male.
  • Males can be housed together but this needs to be achieved at an early age
  • Substrate can be a number of materials. We prefer Aspen.
  • Accessories: Apple tree branches, hides, tubes, and other commercial accessories are available via your pet shop or online.
  • Water and food containers: We opt for a water bottle as this lowers the risk of the bedding/substrate becoming damp and in turn affecting the animal’s health. Food is delivered via the use of a bowl.



Food

  • There are now a number of very good Mouse type diets available.
  • We always supplement our Rodents diets with fresh fruit and veg.
  • Some Livefood should be offered (Crickets or Mealworms)



Breeding

  • Breeding this mouse can be done with some ease
  • Maturity: 8-10 weeks
  • Gestation: Around 35-42 days
  • Litter size: 1-5
  • Unlike other mice the Spiny Mouse gives birth to fully furred babies, which are fully mobile and have their eyes open within 24 hours.
  • Weaning: Because of the advanced stage of their young the Spiny Mouse starts to wean straight away and is fully weaned by 3 weeks.
  • The young are easily identified by their grey coats, which start to moult at 4 weeks. The young will be in full adult fur by 8-9 weeks old.
  • Any females past the age of 24 months should not be mated, as pregnancy to an older female is often fatal.
