Hi Sarah,
I know how you feel! I had two cats (yes past tense) that were my babies. I moved here last year from Utah and was 7 1/2 months pregnant. They were perfect indoor/outdoor cats up until then. It was just too much for the cats. The reason that I'm telling you about them is because we tried EVERYTHING, including the kitty prozac. There were 3 suggestions on here that I had never heard, so they may be where you want to start. The scope cleaning option, which makes sense when you think about it, the CatAttract kitty litter and then getting a big cage and making it the cats home. I know that my cat's were super high strung after we moved so they would have loved their own little space where the kids couldn't get them. Also, there is some professional cleaners that have a special pet cleaner that they can use to take the smell and stains out of the carpet. I don't know how well it works, but it's cheaper than new carpet. I do miss them terribly...until I start reading about all the other problems people have had and realize that we don't have that anymore. Good luck and I hope it all works out for the best!
