Rails - Nov 2007 - multiple categories for a product

I''m currently using acts_as_tree to handle my categories hierarchy.

Animals
   Birds
   Dogs
Themes
   Farm
   City


My product model currently just has a "product_id" column, with an
acts_as_tree object and belongs_to :category

If I wanted to define a product that belonged to more than one category (ie
"Rooster" -- could belong to both Bird and Farm categories
simultaneously),
what is the best way to do this?

farley.barks("very loud");
bonita.barks("at strangers");

Then you need a new model to have a relationship through :)

*something like this*
category <=> categories_products <=> products

and then categories_products should continue only (category_id and 
product_id)
