>I had originally bought one triangle box to serve as a pottycorner. >However, once I put it in the corner they'd chosen, they switched corners. I had a similar problem with my little guy. To cure it I bought a bag of cheap cat balls. I put them in the cage and let him play with themfor a little bit. the I took twist ties and tied them in th eempty corners. Odie, my little fuz, wouldn't relieve himself on his toys so he only had one corner left. hope this helps benjee [Posted in FML issue 1720]
