Nice design. Very unique. One thing though, you may want to rework how your front page works with the layers. Open it up and reduce the width of your browser window. Users on a small monitor will have the "enter" button moved under the cat, thus making it impossible to click on it and enter the site. Maybe switch to static images instead of the layers? Otherwise nice.
I don't know if this is important to you or not, but in Mozilla it has a few issues with things not lining up properly. Looks good in IE, but it's not quite there yet in Mozilla. (see attchmt) Every product page looks much the same, with none of them really coming together properly.
Aside from that, looks like a nice, fun site. Best of luck to you.
I like the layout and graphic for the subject matter. I think you should replace the text with graphic buttons and also replace the buy now links with buy now buttons. It looks more pleasing to the eye to see that all they have to do to buy is click a button then a small text link.
