Query: Sold on Citikitty

We have two white kitties, Sam and Snow. They're brothers and we rescue/adopted them at six weeks old. They were not full adults, but weren't kittens either and someone recommended CityKitty. We followed all the steps and gave them all the time they needed. Yes, it is messy while you're doing it. We kept a broom and dustpan in the bathroom, but it was well worth it. We kept a close eye on their toilet at all times, making sure it was clean and they would not "use it" somewhere else because it was too messy for them. They were fully trained in about two months. What a relief not to have to deal with the litter box anymore. We have recommended it to all our friends with indoor cats.
