Sounds like you need to develop your own post filter collector. In this collector you can get value for your field cat_id by document id, store it in collection and filter out documents which values are presented in this collection. It similar with http://lucidworks.com/blog/custom-security-filtering-in-solr/ , but other custom logic.
