What's the one category that most closely matches the focus of the site?
A few outlying products doesn't change the focus. If you sell, say, 100 different flavors of fractionally distilled dog poison and one style of handcrafted jewelled rat collar, then the site isn't going to be listed under "generic pets" or "supplies" -- it's still going to be under Dog Food.
If you aren't absolutely clear that you have found the one site that best fits, then DO NOT RESUBMIT. The editors already have a submittal: if they have to find the right place for it, then you've already done all that you can do, so stop. Again, the ONLY reason for resubmitting is if you are SURE that you KNOW the ONE right category, because you KNOW a GOOD reason why EVERY other category is not plausible.
