A great place to start would be petfinder.com. Many rescue groups and shelters use the site to showcase pets that they have available. That will also link you to the names of rescue groups and shelters close to you. It will also tell you a little bit about the cat, like if the cat is good with kids. Many fosters have children that interact with the cats. You can call rescues or shelters and tell them your situation and they should be able to recommend something for you. It shouldn't be a problem finding the perfect cat(s) for you. There are so many great cats in need of homes right now. It sounds like an older pair would be better for you since kittens are definately a handful and can get into loads of trouble in a big house.
