Classification is a scientific hypothesis
Taxonomy groups organisms using evidence about their relationships and differences. Genetic work, morphology and geography can lead researchers to reconsider older arrangements.
Splitting and grouping change totals
A population once treated as a subspecies may be recognized as a separate species, or previously separate names may be grouped. Different references can therefore give different totals without referring to different animals on the ground.
Use a stated reference
The initial wild-cat index follows the 40-species scope presented by the IUCN SSC Cat Specialist Group’s living-species page and its 2017 classification framework. It is a reference scope, not a claim that classification will never change.
Keep names traceable
Common names vary between languages. Scientific names and source links help readers connect entries. Editors should document updates rather than silently changing the meaning of an existing page.
A useful next step
Choose one manageable improvement and make a note of what changes. Use the practical tools to organize the details, and return to the discussion to share what you learned.
