Heh heh...sorry, I was sort of stuck, and having missed the deadline...I've got a video of B.M. doing "Copacabana" which I put on when I need a good laugh.
"He's SO sincere!!!" *sigh* :)
(Put on the video AND follow kitty with a zip lock bag while dancing to Copacabana?!?!?!)
I think for the video: both manilow and following kitty with a bag simultaneously would be a show stopper.
That would make one funny home video....lol
lol you can do like i do, put the litter box in front of the tv and sit and watchtv. wait until cat enters the box.....make sure you have a zip top bag handy...... when cat proceeds to do the dance, they pick their real estate, and build a house..... bring out bag and catch said poo. its fresh and untainted with dirty infected litter. its funny, and scares the cat a few times, but i take away all other boxes and soon enough, they wont mind you behind them with a bag.
Got here to late for this...but I'll say right now I'll be damned if I know. Sing Barry Manilow songs to kitty? :)
Seriously, the only thing I can think of would involve medication which would probably invalidate the test.
