In Venezuela agoutis breed throughout the year. Females have an average estrous cycle of about 34 days, with gestation lasting around 104 to 120 days. They also experience postpartum estrus. Litters are usually made up of one or two young, sometimes three occurs. Newborns are fully furred, have their eyes open and are able to run in their first hour of life. Females lactate for about twenty weeks.

Agoutis are basically diurnal, but in areas where they have been affected by humans they may not leave their shelters until dusk. They are terrestrial and are adapted for a cursorial life. They walk, trot or gallop on their digits, and also can jump vertically at least two meters from a standing start. Aggression increases in adults at the onset of every new litter. This is caused by the shortage of available food. During courtship rituals, the male sprays the female with urine causing her to go into a frenzy dance.

Agoutis tame easily and make good pets. They are also extensively hunted for food.

In some areas, they have declined drastically due to habitat destruction and hunting.
