How to create blogs showcase/network website?

Hello

I am interested in pets. I constantly look for blogs that deal with how to take care of cats. I believe many people do the same, and constantly browser tens of blogs that touch on the same subject.

What I want is to create a WP blog, which shows the last posts from a number of blogs that deal with pets. I dont want this new WP installation to simply give links, or excerpts. I want my new blog to show the whole post inline, with the title of that post pointing to the source blog.
Whenever there is a newer post from another blog, I want that newer post to be displayed on top of my new blog’s index, and the older one to appear after it, in the index, just like an ordinary blog, but with posts coming rather from different blogs.

Is there a way to do that ?

Thank you
