Suggest another litter tray. my two needed one each as otherwise
mistoffelees used to sit in the tray deliberately to keep grizzy out. they
used to fight over who got to use the tray first after it had been cleaned.
A second tray meant that i didnt have to clean the kitchen lino everydy and
work out what grizzy had peed on

First of all, you need to have two boxes. Second, you must clean the urine
using an enzimatic cleaner to get rid of all the smell. Then spray with
Feliway, it helps prevent accidents.

Start with a vet check in case she has a urinary infection or other
medical problem.  Then start visiting sites like the FAB
(www.fabcats.org I think) and Messybeast (www.messybeast.com) which have
lots of good information on this kind of problem - you will find the
advice in the other posts in this thread include some of the ideas
there.

Also use biological washing (laundry) powder to clean the soiled areas,
but to a spot check first to make sure it won't remove colour as well.
If the carpet is cheap and well-worn it might be time for a new one, or
for a vinyl or other washable floor covering.

Each should have its own litter tray and these should be well away
from food, water or their beds/baskets.
Clean and deodourise the used corners with *non-chlorine* bleach
(Parazone, Domestos) and diluted white vinegar to remove the residula
scent.  Chlorine-bleaches break down into components which smell a bit
like cat pee (usually too faint for humans to detect0 and this can
drive a cat into a frenzy of scent marking.
Place bowls of food (biscuit) in the cleaned areas - few cats will pee
where they eat.
If possible, consider putting the litter tray(s) in one or other of
the chosen corners.
Check that the cat isn't getting territorial due to other cats
entering the house.

At the same time as taking steps to clean and prevent the problem, get
the vet to check over the female for cystitis - this makes cats want
to pee all the time, and often they won't make it to the litter tray.

If she won't bond with the litter tray, get hold of the Peter Neville
"Do Cats Need Shrinks" book for some ideas.  There is a multi-stage
process for teaching the cat to use the tray (snipped from a previous
post):

There is a step by step program for re-bonding a cat with the litter
tray.

1.  Confine cat to kitten pen (large cage) which contains his bed,
food and water.  The rest of the kitten pen floor must be covered in
litter.  The only place he can pee is in his bed or on the litter.
Only allow him out *after* he has peed (if he still pees outside, it
is marking behaviour which different altogether).  During this time,
deodourise the house and /clean articles he has peed on.

2.  After about a week, instead of litter on the kitten cage floor,
put it in a litter tray.  If he has bonded to the litter, he will use
the tray.  If not - it's back to step 1 for another week.

3.  When he is consistently using the tray, confine him to a single,
easily cleaned room with his bed, food/water and litter tray.  If he
reverts, it's back to step 2.

4.  Once he consistently uses the tray he can have more freedom.
Avoid leaving around any triggers for bad toileting - newspapers etc -
until he is absolutely reformed.  There's owner lifestyle modification
needed too.
