Well that was educational!
I didn't think of all the implications. True that it'd be difficult to see any poop blood or to check ..ahemm...around the tray for abnormalities.
And also, can you imagine having to queu up for the toilet waiting for kitty to be done???
Endless agruments...
I don't think they'd fall in, but as I have 4 training them one by one would be impossible, also cause the ad says to remove the tray altogether, and just leave the Kwitter on. That would get me a lot of stained carpets...
And true, the baby seat would do just as well!
Thanks folks, you are a creative bunch!
