Any advice?

I'm not sure where to post this so I hope I am putting it in a ok spot. My cat had 5 kittens a week and 5 days ago. All are doing great! However towards the end of her pregnancy she used my concrete laundry room floor as a liter box. I figured it was just a few accidents due to pressure on the bladder. Well she is still doing it now!! She was given a clean bill of health so thats not the problem. Easy answer would be to closed the door but I am remodeling still from the hurricane and it makes it hard. Plus if the door is closed she will try to find clothes to use!! She has 2 liter boxes in the house all to herself but there clean she hasen't used them. I tried different liter and everything. I'm going crazy and don't know what to do! Any suggestions?

Take a look at this thread by Hissy: http://www.thecatsite.com/forums/showthread.php?t=9563 It has tons of advice for the specific problem you're talking about. The first thing you do need to do is to clean the area with an enzyme cleaner like Nature's Miracle or ZeroOdor or similar. This will help her to not associate the area with elimination. Since every situation is slightly different, the thread is a good place to get all steps after that.

As far as clean bill of health, did they specifically look for a bladder infection? Also, it helped a lot with this problem when we got my cat spayed. Another thing is that for some reason cleaners, especially bleach, attract cats because to them it smells like urine. That's one reason why cats often pee on clean laundry. Other things - have you changed her litter or moved the litter box? And last but not least, cats will not eliminate where they eat, so you could either move her box further away from the food, or move her food to where she is going.

When we had this problem, the solution was that the cat needed a box on every floor of the house - she couldn't make it when she was on the middle floor!
