[Sca-cooks] Cat Litter substitute

[Suey]

    I have a 7 week old kitten, perfectly trained in his box¡ but I have 
a plastic trainer seat sent from the states. You put it on top of the 
toilet with cat litter when the cat is 3 months old and can jump more 
easily. The first week it has no hole so he covers his excretions as 
normal.. The second week you open a perforated hole in the middle and 
the second week another bigger one, less litter each week, etc until you 
only have the size of a human toilet seat left. Then you remove the 
plastic seat and he does his thing on your toilet seat. The problem is 
that Chile does not sell flushable cat litter. Frustrated, I thought I 
would order some from the states. A 4 lb bag costs $8.00, shipment is 
some $200 to mail to Santiago!
    I consulted the pillow. I am wondering if flour can not substitute 
litter in the training seat. Then I see things like oatmeal, wheat, 
split peas (flour?). . .  other mentions are beyond my knowledge in 
finding them such as natural pine pellets and paper pellets. The bottom 
line is that whatever goes into that training seat has to be flushable 
and I have to be able to find them!
    Any suggestions are most welcome.
