Automatic Litterbox Central

I purchased my LR in January for my 2 cats. The male is using it without any problem but the female goes in and tinkles but then comes out and poops on the floor. I know some cats do not like to pee and poop in the same box but I do not want to put out another litter box. Does anyone have suggestions how to get Miss Callie to do all her business in the LR.
I would want another LR if 2 is the answer, but the price even for reconditioned ones are making that impossible. Has anyone else experieced this?
Thanks,
Marilyn

What I did was provide a second litter box -- nonelectric-- right next to the LR. My cat used both for about a year before changing and using the LR exclusively. You might give that a try -- better than having the cat get into the habit of pooping outside the litter box.

many cats do not like the dirty nature of the LR.

It rotates the crap around the complete inside of the machine making it real nasty inside (especially with multiple cats)

If your cat like to go inside completly, they are likely to end up not using it.

the next step will be that your cat pisses outside too, mine suffered with the LR for peeing but when she could not stand it anymore she would do that outside the LR too!

back to the old hand clean box...

right now this business is wideopen for a reliable solution! there is none right now in all instances but the LR comes close-
