The .cat TLD was introduced in 2005 in order to help promote the Catalan language and culture.
Catalan is the official language of a Spanish region, including the independent nation of Andorra.
When ICANN approved of .cat, it set forth some rules.
According to Wikipedia:
In order to be granted a .cat domain, one needs to belong to the Catalan linguistic and cultural community on the Internet.
A person, organization or company is considered to belong if they:
- already have content in Catalan published online.
- have access to a special code (sometimes called ENS), issued during special promotions or by agreements with certain institutions.
- develop activities (in any language) to promote the Catalan culture and language.
- are endorsed by 3 people or 1 institution already using a .cat domain name.
However, this doesn’t seem to be followed strictly, as the domain Kitty.cat proves 😀
