A few things come to mind. First, has he been vet checked to rule out any
illness? Second, has he been neutered yet? Also, (no offense), are the boxes
clean enough for him? Most cats are extremely particular about the
cleanliness of the box. Have you tried different litters? There is a litter
called Cat Attract that works well for cats with a litter box aversion.

You can try these links....they might contain some helpful info you haven't
tried yet.

Hope you can resolve this soon.

Marking
Cats in the wild use marking as a way to communicate with one another. The
actual process of marking can take a few different forms from scratching to
spraying. A common marking behavior is spraying. Spray is actually created
when the cat mixes a small amount of urine with glandular secretions called
pheromones. These are the components that make cat spray have its
distinctive and potent odor. Other common marking behaviors are leaving
pheromone and/or visual markers through scratching and rubbing against
objects. Marking with feces can also occur, although this is seen less
frequently.
Pheromones play a very large role in a marking and a feline's life. Cats use
these pheromones to mark their territory in many ways. Cats have glands that
produce pheromones on their mouths, chin, face, cheeks, ears, paw pads, anal
area, and upper surface of the tail. When your cat rubs up against you, or
rubs up against your furniture he is actually leaving a little trace of
pheromones that say, 'this is mine', in a friendly way. When a cat scratches
he is not only leaving a mark through pheromones, but he is also leaving a
visual marker that says, 'this is mine!'. Spraying is another way for cats
to release pheromone, however, this way usually meant to say, 'stay out', in
a more defensive tone.

Cats of both sexes (although males tend to mark more than females) mark as a
sign to other cats that a certain territory is theirs and/or that they are
the dominant cat in the area. Cats in heat and males responding to a cat in
heat will do a lot of marking as they go on their quest to find a mate.

It is fairly simple to break a cat of bad scratching habits (see scratching
area for specifics), and urine or fecal marking behavior (both however do
require time and patience). In most cases spaying or neutering the cat will
be enough to stop him/her from marking. If that doesn't fix the situation
try to reduce your cat's need to mark by making sure your cat feels his/her
territory is sound and that his/her dominant position (or position in the
hierarchy) is safe. This means you will need to figure out why he/she is
marking (is there a new cat in the home, can he see another cat from a
window, did you just get a new pet, are you favoring another cat who isn't
the 'dominant' one) and then try to combat the problem from that route.

If your cat has marked quite a bit in the past you will need to remove all
signs of the mark using a special odor controlling solution. Although you
may feel you have cleaned the area thoroughly and that it smells fine, cats
have a keen sense of smell and will most likely still designate the area as
being marked unless you have used an odor neutralizing solution designed for
cat urine and spray. Until the area is truly clean your cat will continue to
go back to it and re-mark. You can purchase such products at your local pet
store. You can also help your cat stay away from the spot by spraying it
with a vet-approved cat repellant which can also be found at your local pet
store. For specific information on dealing with problem spraying behaviors

Note: Cats can mark due to illness. So before you start trying to correct
marking from a behavioral standpoint take your cat to the vet to rule out
any sort of health problem that could be the culprit.

Hallo Colby,

Alittle cat needs more then 1 litterbox.
When he has to pee, he must find very quick a litter box . When there is no
box near him, he uses the karpet.
Give the first  months a few litterboxes.
You shall see that its soon over.

Good luck
