The food-handling and reingestive behaviour of feces by Ctenomys pearsoni Lessa and Langguth, 1983, was studied in the laboratory. All animals studied handle grasses with dexterity with one or both forepaws, and vigorously shaked it up and down before ingestion. Reingestion of feces occur frequently during resting periods and between feeding bouts. While performing both behaviours, C. pearsoni adopt a posture that not increase its height, what could be considered as and adaptation to the burrow space. Some convergences and divergences in the patterns of food-handling and reingestion of feces between Ctenomys and other subterranean rodents genera were remarked. We propose that the food-handling pattern is related to the cleaning of food; while the reingestion pattern might be related to water economy and to recover some particular nutrients.
