I just wrote this as an answer to a member and thought it's kind of a frequently asked question here 
The arabic downloads, they are all in .cat because they were created by me using little reader and need little reader to open. You can download the little reader lite free version here:
http://forum.brillkids.com/announcements/little-reader-lite-is-now-officially-launched!-t2245/However, you'll need little reader home basic to be able to download and open ALL the arabic downloads that I made Here's a search for arabic downloads on the downloads page:

after seeing LR lite, if you want to, you can upgrade to LR home by either paying OR using the forum to gain loyalty points and get discounts or get it for free even!
Here are 2 links that explain the loyalty points:
