Am not asking for the usual type of help to get a cat to use it but to
leave it alone!!

Ever since I got him he has had a fixation for litter boxes.  When he
was small (Like 9 / 10 weeks) he used to lay in it, play in it, ETC.
He would get chasing his tail and litter would go everywhere!!

Now at about 5 years he checks them out often and if the others do not
do a good job burying it he will do it which is not bad but he digs
until every bit of litter (Literally) is in a pile and lots of time if
it is by edge of boxes it will be on floor.  I often am up the middle
of the night cleaning floors around litter boxes!!!  I try to scoop
the boxes whenever I see them use them so their is no reason for him
to but mainly at night or when I am away he does it!!

Often times he will not even wait until the others are done but start
burying while they are still in the box useing it.  I keep waiting for
him to get his nose peed on or worse!!!

I have tried covered boxes but they will not go in them and are afraid
of the automatic ones (The noise).  I have even tryed water and noise
on him but then occassionaly the others will run from box even if they
are in middle of job!!  They are all VERY scittish (SP).

What with this fixation and the other problems he causing I am on the
edge of rehoming him!!!  I really do not want to because I love him to
death but am getting to old to put up with him!!!

He thinks he is the top cat here and acts like it.  He attacks the
others, chases them, ETC.  He bit one of the others when smaller and
she needed a tube the length of her belly to drain infection out.  The
others are all females.  The 17 year old one will not come out of
bedroom when he is up and around.

Anyway I am really looking for solution to the litter box problem.
The rest I can deal with!!  :-(
