I think the first item in the site’s FAQ sums them up perfectly well:

What do you do?

I make art out of dead animals and other nice things. YOU buy the art, then I take the money and go buy gin. See how simple it is?

In addition to a neat gallery of work, the site also includes instructions on making one’s own “deadgarden” to clean and give character to animal bones. The writing style is chatty and funny, and I’m strangely taken with Robert, The Best Dead Cat In The Whole World, featured on the home page.
