She is probably reacting to the previous cats that lived there. I'll bet if you asked, the other cats probably pee'd in those same spots.

There are a few things you can do. First take her to the vet and make sure that she doesn't have a urinary tract infection and is trying to tell you something.

Have you recently changed the type or brand of litter (or litter box) that she is using? She might not like the new one...

Then I would get that area of the carpet steam cleaned. If you do it yourself, make sure to use the special animal cleaner that they sell. Then make sure she doesn't go into that area until the carpets are dried (but I think that will take care of itself ).

I am not sure what cleaning products you are using, but after much trial and error I found that the Woolite brand of pet cleaner works for me and my gang.

I would also consider trying different types of litter to see if there is one she prefers (the things we do for our animals ).

There is a whole process of re-training, but before you go that far I would try some of these suggestions first.

Don't worry we all go through this at sometime or another...
