Visitors' perceptions of zoo-housed lesser anteater (Tamandua tetradactyla) welfare: Observation plays a larger role than a brief informative talk.

There is a growing ethical concern in modern society about animals' quality of life.

Visitors observing active lesser anteaters in their enclosures at Córdoba Zoo (Argentina) were asked to respond to a questionnaire about animal welfare.
