Visual acuity of the northern native cat (Dasyurus hallucatus)--behavioural and anatomical estimates.

Behavioural estimates of the visual acuity of the Northern Native Cat (or Northern Quoll)--Dasyurus hallucatus--were made using the Mitchell jumping stand technique. A value of 2.3-2.8 cycles per degree was obtained. This functional acuity compared well with predictions based on the peak ganglion cell density (2600 cells/mm2) determined from the retinal ganglion cell density map.
