I've found this nifty website dedicated to Ta'agra, the language of the Khajiits. It's a great resource for those who are into Khajiit role-playing, or for those with interest in conlangs in general.
The lexicon is quite big and the grammar looks ready enough to be used in conversations.
Here's the link:
