Query: read if more than 1 cat

I had one kitty and she did pretty good-she is a fairly neat cat. I needed to empty about once a week-don't let the receptacle get too full because if you do and try to get it out...you will be slinging poo all over. So everything is going fine until Frank joined the family. Frank was a beautiful Siamese baby who showed up at my office. Sweet and with a hernia. Frank has single handidly broken two boxes and I swear I had to empty almost everyday. I think he loved the thing so much he went all the time. I also bought one for my brother. Patch was able to break his first one overnight. The second one broke in a week. My brother would like to offer Patch as a test cat to litter-maid. I have never seen anything like it. So, I think it depends on the unit you get and the cat you have. I have gone back to the original litter in a plain box. Good Luck.
