These are the same as the animals commonly called Spiny Mice. Their real name is Acomys cahirinus . When you talk about spiny mice you are probably referring to Acomys cahirinus and its subspecies. You can find wild spiny mice in Africa, Asia and the southern parts of Europe. The species is active during the night.
Spiny mice are generally very social in the wild.
Males live together without fights if the cage is large enough, they only fight if the cage is too small. The best cage is a big aquarium, since these animals thrive in heat and aquariums keep in the heat. Spiny mice can die at a temperature of 10 or 15 degrees Celsius. They prefer temperatures around 30 to 40 degrees Celcius. To burrow toilet rolls and stuff like that in the bedding is a good idea, so it will be easier for the mice to make tunnels.
