Can i vent here for a moment, I'm going to anyway.  :)

Ya know how with the litter maid it works best if you do not fill it to the
full line.   Well we've been using ours for 6 months now and I discovered
that within the first couple months.   YET, tonight I go to check the
litter.  (and Sabrina hasn't used it since early morning, as she was at the
vet all day) there's 4 pee's and 2 poops in the litter - and the thing is
"confused" again.  So that is at least 1 day's worth (last check must have
been either Sunday or Monday night), non of which got swept up like it
should have,  Why, because BF filled the damned thing too full again.    How
many times do you have to tell men these things before it sinks into that
bull head of theirs?   Don't fill the darned thing so full, and push the
litter towards the back and then turn the littermaid on, let it sweep the
litter forward and spread it itself.
