How to browse to a specific post with signed by two categories?

Hi,

I have a WordPress blog and I catalog the posts by categories.

Later, I can browse directly to any category (?cat=nn) from within the URL , and I’m wondering if it’s possible to browse to posts which contain more than one category?

e.g.
I have a post which was cataloged by two categories: food and dogs. Now I want to present this one only, but specifing the right categories in the URL Is that possible?

Thanks
