[4] This species is primarily found in steppic, uncultivated xerophilous landscapes of South-Eastern Romania's Dobruja region and North-Eastern Bulgaria, often inhabiting lowlands along the right bank of the Danube River, while occasionally venturing into cultivated lands such as alfalfa fields and corn cultures.

These hamsters lead a solitary lifestyle, meeting primarily for mating purposes, and are known for their intricate burrow systems, which serve as both shelter and storage for food.

This storage behavior serves as a crucial survival strategy for Romanian hamsters to evade predators and navigate challenging environmental conditions.

Reaching sexual maturity at a relatively young age, typically between 56 and 70 days old, Romanian hamsters engage in breeding from early April to August.

Communication among Romanian hamsters primarily involves squeaking sounds and ultrasonic vocalizations, which facilitate social interaction and territory marking.
