Stand-alone stores do not get as much business as markets. Market traffic is pretty essential. I have a stand-alone store, but mainly use it as a hub where I organize boxes and have my Cattery dock and some cats before bringing things out to some markets. Being in a market also lets you check to see if your prices are in line with what others are charging.
To get your name out: post here with pictures of your cats in the showroom section. Have a link to your store in your signature. Offer cats at auctions if you have time to do that. Some people post quite actively to flickr with pretty pics of their cats. Post cats on the Live sales section here.
I'm sure others can offer more suggestions. Good luck.
