Why are degus illegal in some states?

Degus are illegal in some U.S. states and certain regions of Canada primarily because they are classified as invasive species. This classification means there's a concern that if degus escape into the wild, they could establish populations that harm the local ecosystem.

While degus have gained popularity as pets only in the past decade or so, similar to their relatives like chinchillas and guinea pigs, some jurisdictions impose strict prohibitions on their ownership.

Understanding the "Invasive Species" Classification

An invasive species is an organism that is not native to a particular ecosystem and causes, or is likely to cause, economic or environmental harm or harm to human health. When a non-native species, like the degu, is introduced to a new environment, it might:

• Outcompete native species: Degus are highly adaptable, prolific breeders, and efficient foragers. If they establish wild populations, they could compete with native wildlife for food resources and habitat.
• Spread diseases: They could potentially carry diseases that native wildlife or even livestock are not resistant to.
• Damage agriculture or infrastructure: In their native habitats, degus are known to burrow extensively and consume a variety of plant matter. If they escape and form wild colonies, they could damage crops or undermine structures through their burrowing activities.

The concern is that once a non-native species establishes itself, it can be extremely difficult and costly to control or eradicate, leading to long-term ecological and economic damage.

Jurisdictions Where Degus Are Prohibited

Several states in the U.S. and some Canadian areas have laws against owning degus to prevent these potential ecological threats.

These prohibitions are a proactive measure to protect local biodiversity and agricultural interests by preventing the establishment of non-native wild populations of degus.
