Here's why:
* Wide Range: Fennec foxes live across a vast area of the Sahara Desert and other arid regions in North Africa.
* Difficult to Track: They are nocturnal and elusive, making it challenging to get accurate population counts.
* Lack of Comprehensive Studies: There hasn't been a large-scale, comprehensive study to estimate their population size.
However, the IUCN (International Union for Conservation of Nature) lists the fennec fox as "Least Concern" for conservation status, meaning that their population is not considered to be at immediate risk of extinction.
While we don't know the exact number, it is likely that their population is relatively stable, though they face threats like habitat loss and illegal pet trade.
