Degus are lively rodents native to Chile, roughly the size of a large gerbil. These sociable pets thrive on interaction, both with their human companions and fellow degus, making them ideal for those who want an interactive small animal.
Degus require spacious cages and plenty of enrichment, such as tunnels and chew toys, to keep them mentally and physically stimulated. Their intelligence and playful nature make them endlessly entertaining.
