grrr IE Display problem

[The Geek]

Hi Guys, been working all weekend on my new GeekMart project as I have to have it operational tonight. The last bug bear is that I just checked it in ie (been deving in ff) and am coming up with this moronic spacer as between some of the borders and the cat heads. My brain is shot and I cant see the wood for the trees can anyone help with some HTML to spot the waldo in the code?



here is an example page: (notice the add to cart oddity)
