I am happy to report that after moving the litter box into the bathroom, Patty has been a real “pooper”. (Pardon the lame play on words with trouper and pooper.)
So… the CityKitty kit arrived today. 

The kit includes the CitiKitty tray, instruction manual, tips sheet and a small package of catnip.
One of the things that they don’t tell you on their web site is that when you move the litter box into the bathroom, you should switch to flushable litter. Then, when the training kit arrives you cat will be accustomed to the new litter.
Being the impatient person I am, I just couldn’t wait another week to get Patrick weened to the new litter, so I jumped right into the challenge… hopped into my car and headed to Target for flushable litter. After reading the back of dozens of litter packages, I found that only one was flushable. And the winner is…
Swheat Scoop Natural Wheat Litter
Here’s the tray sans litter…

… and here we are with 1/2 inch or so of litter and some sprinkles of catnip.

The next step was to introduce Pat to his new “box”. I am fairly certain that he has been around the toilet bowl before and he knows that it contains WATER. If you’ve ever had a cat, you’ll find that H2O is liquid evil to many cats… and Patty is no exception. So… his claws come out because he fears I am throwing him to the (wet) wolves. Then, he realized… “Hey… where’s the water?”… sniffed around a bit and jumped down.
I lured him back with treats.

I have seen him back on the toilet a couple of times now. Is he looking for food? Will he do the deed?
Stay Tuned!
UPDATE (2/5): Patty isn’t “feeling” the new litter, so I moved his litter box back into the bathroom (with the new litter) to give him a few days to get the feel of it.
