We recently moved to a new house, and after about a week of our cat testing out the new territory, he disappeared for 24 hours, which had never happened before. We tried "Lost My Kitty" and a couple of other services, and "Lost My Kitty" was the only one we felt wasn't a scam trap. Specifically, the other services flooded us with "We found your cat, send me your personal contact information," whereas "Lost My Kitty" did a great job of filtering that out and providing us with a-la-carte options that made sense for us. Fortunately, our cat returned on his own, but we wouldn't hesitate to use this service again if we could not find our cat.
