What's that smell?

In this note on the Nobel in medicine, PZ Myers mentions that about 3% of the human genome is devoted to smell receptors. And that's not counting the broken remnants of genes formerly encoding smell receptors; our ancestors relied on it more.

I wonder how much of the cat genome is smell receptors.

I checked out the press release; it's 3% of the genes, not 3% of the genome. This initially struck me as funny because only about 1% of our genome consists of genes.
