The historical paucity of data has led to inconsistencies and perpetuated inaccuracies in current literature, which in turn has affected the accuracy of conservation measures.The naturally rare, cryptic colouring, small size and secretive nocturnal nature of this species has contributed considerably to the lack of information.

Prior to 2000, there are only 251 specimen records including fossil specimens were available for the species.

Since then, more than 545 records have been collected with an emphasis on locality data have been recorded.

However, defining subpopulations for this species needs further work.

We also caution that these estimates will be confounded by uneven sampling across the range, thus leading to inaccurate density isopleths.

For Nuwejaarsfontein, density was estimated at 0.06 cats / km² from 2009-2014 (Sliwa 2004, Sliwa , 2014). Using these density estimates, population size was calculated by converting kernel densities based on verified records (both historical and recent) to high (0.03 cats / km²), medium (0.02 cats / km²) and low density (0.01 cats / km²) isopleths in Arc GIS across the entire range of the species in the assessment region.

However, these two sites may represent exceptionally high densities due to favourable climate and human management, and low-quality habitat densities are probably much lower (Sliwa 2013). The population sizes from the density bands were then summed to produce an overall population estimate.It is now clear that the species has been previously under-sampled.Throughout its entire range there are only 692 verifiable locality records which can be reliably mapped (Wilson 2016).On the eastern side of its range, occurrence records are confirmed to just west of the Kruger National Park, into north-western Kwa Zulu-Natal, and new data suggest that the species occurs further south and south-westwards in the Southern Cape and more westwards in the Northern Cape than previously realised (Wilson 2016). Camera trapping for this species is particularly difficult due to secretive behaviour and small size. Black-footed Cats move quickly and do not habitually use game tracks or roads like other animals.For example, in over 790 records, only one was from a camera trap (B. Since 2006, there has been extensive effort to establish the historical and current distribution of the species (Wilson 2016).Black-footed Cats are known to occur at low densities and it is difficult to establish population sizes.
