Degus come from Chile. They live in herds and inhabit the slopes of the Andes up to an elevation of 1200 m where they build burrows consisting of a network of tunnels. They were brought to Europe for science purposes, in relation to the studies on diabetes. Degus are extremely sociable and active; they are moving all day. These rodents soon become tame and learn to recognize their owner. Nevertheless, they will not stay on his/her knees for too long. They will probably not cause allergy as their fur is not a significant allergen. It is important never to try to catch a degu by the tail because it will fall off easily and never grow back. The biggest attraction is to observe these rodents in a group: their playing, rows and “conversations”. According to scientists, in every degu community there is a hierarchical structure and they also have some specific speech. Exposed to predators’ attacks, degus live approximately 1-4 years in the wild and 5-9 years at home with special care and appropriate food. Owing to their inborn tendency to diabetes, their diet has to be precisely composed and resemble food they eat in their natural habitat: grass, leaves and seeds. Similarly to diabetics, their food cannot be fat or have a high glycemic index (that increases blood sugar). Degus mustn’t eat food intended for other rodents – it has to be developed individually for them.
