Do you post pictures of your cat on Saturdays, in celebration of the internet Sabbath known as #Caturday?
I Know Where Your Cat Lives is a website devoted to mapping the cats of the world, based on mapping the geo-location information in a million publicly available cat pictures found on the Internet.
If you infer a warning from this, you are correct.
This picture never had any geo-info to remove, because Apple defaults toward protecting privacy (mostly). But not all phones behave the same: check your settings.
