Well, I've officially moved to Dallas. The ride was long - Pascha went #2 twice in the car on the way, but fortunately with regards to the toilet training it seems that the Litter Quitter has been a huge success both in Austin and now in Dallas as well.
Because we had prior training, we started the cats out in Austin on the Yellow, intermediate ring. That worked wonderfully, and we kept them on it throuought the move so as not to change it up too quickly on them.
In Dallas, we introduced them to the house by keeping them in my bedroom and bathroom at first. The Litter Quitter was totally transferable (though it didn't fit as well on the toilet), but unfortunately so was my sink. Pascha instinctively found the sink and has only used that to pee in. The good news is that she seems to understand the difference between using the sink for pee and the toilet for poop. Honestly, if that's the way it has to be, I know it could be worse and so I'm alright with the outcome.
They've been in Dallas almost a week. Bathroom use is normal, instinctive, and they don't appear to want to go anywhere else (other than the sink for Pasch, of course). I yesterday moved them to the next level, and just discovered that it works well. Pascha let her foot slip in the toilet once, but it was before she used the bathroom and I still think she is pleased with how little the toilet releases smell. Time will only tell to know if this foot slip was devastating or not.
