Range
As stated in the name, its range is the Andes Mountains in the west of South America and as indicated in red (and extended by a blue line) on the map below, which is an embedded Google map created by me. The range is a refined version based on the IUCN Red List and should be good at Update 10 Feb 2010:the additional area within the blue line is due to recent research by Jim Sanderson PhD and his team. You can refine it if you have the knowledge to do so.

Update Dec 2021. Below is an updated map from the IUCN Red List of the Andean mountain distribution:

The Andes covers these countries: Argentina; Bolivia; Chile; Peru. The distribution of this cat is restricted to the higher areas of the Andes. The range map below is one I made earlier.
These are the heights at which this cat has been seen in the countries mentioned:
Country – Area | Height above sea level – meters |
Argentina | 4,236 |
Southern Andes | 1,800 |
Chile | 3,714 to 4,414 |
Bolivia | 4,100 + |
Peru | 4,000 + |
The range in Peru has been found to extend from the far south to 800 kms away in the center of Peru. The records of distribution are down to the efforts of the Andean Cat Alliance (www.gatoandino.org). Although, sightings of this scarce cat are very rare. Apparently less than 2500 cats are believed to exist.
I think you are right. I uploaded that ages ago. I’ll change it now and thanks.
I think that’s actually a pampas cat in the first picture. I see them get confused with Andean mountain cats alot.
Sincere apologies for the typo. Working at speed is the problem. I have corrected it and thanks for allowing me to use it. Copyright is dead on the internet in my view because Pinterest and Google Images destroyed it as a legal concept.
You can use my picture, but please spell my name right. Thank you
