Just about every time I clean the litter box I find clumps on the sides,
however they break away cleanly if I am careful about removing the
surrounding litter that supports the clump and remove it.

I use Purina Maxx Scoop Multi-Cat Formula. It is a clumping litter. I
only have one cat, but use the multi-cat formula anyways... I find in my
area it costs the same as the regular. It is available in an 11kg box or
7kg pail.

I fill the pan with enough litter such that it is rare if anything
actually gets to the bottom... when it does the pan is usually running
low on litter.

I've had good success with this litter.

I don't have any experience with natural biodegradable litters, but I do
have some experience with clumps stuck to the sides of littler boxes.  Until
you find a litter that meets your needs, you could try switching to a larger
box (if you aren't already using one) so your cat has more room in it.  I
had two boxes--one standard sized one (the type most people buy when they
first get their cat) and one of those covered ones.  My cat not only peed
against the side of the first box, she also tended to pee over the side so I
got the covered one but used it without the lid.  Then she no longer peed
over the side, but still peed against the side.  I finally got a big
Rubbermaid-type box that was about 2 or 2.5 feet long and 1.5 feet wide, but
only maybe 4" deep.  It's perfect for her and I don't have to deal with
clumps stuck to the side of the box.

I use Swheat Scoop.  I use those big black garbage bags and stick the box
inside the bag, then pour the litter inside.  The garbage bag acts as a
litterbox liner.  Then when you empty the box, just turn the bag inside out so
the litter is now inside.  Also, you can spray the inside of the box with
non-stick cooking spray to keep it from sticking.  I find that using about 3
inches of litter keeps it from sticking too.

The Swheat scoop clumps very well.  It clumps better than clay litter, in my
experience. I have 11 cats using 1 litter box, which is a rubbermaid tub
about 3 feet long and 2 feet high.  I keep 6 or more inches in the box.

Yes, the cats spray the sides and yes the swheat scoop sticks.  BUT--it does
scrape off easily.  It does not break into little globules.  And most of all
it just doesn't smell when wet.  An added benefit is that swheat scoop is
lighter so it is easier for me to dig through to remove the clumps.

It is totally biodegradable.  However, how do you intend to recycle it?
Most municipalities burn or bury their garbage.  If you throw it out, it
will probably be in a plastic bag, and that won't degrade.  I would NOT
recommend flushing it.  I've tried and fortunately lived to tell the tale,
but it can be an expensive plumbing issue, despite claims on the box.

I'm extremely environment oriented, and I like the fact that this litter is
made from what would otherwise be a waste product.

I clean the box once a day.  I NEVER fully empty or scrub the box.  Why
should I?  The whole idea of clumping litter is that one shouldn't have to
do this.  With the old kind of litter (non-clumping), I had to dump and
scrub the stinky box at least every day.  My cats are extremely healthy.
When you think about what cats get into and how they clean themselves, why
on earth would you worry about disinfecting a litter box!  In fact, there is
much evidence to support the theory that modern day "cleanliness" is
responsible for most of our auto-immune diseases.

I find that if I prepare the boxes as recommended - 3 inches deep and use
cooking oil spray on the box interior before adding the litter - that the
Swheat works pretty well.  Daily scooping is required.  If I'm away for
the weekend, clumps on the sides of the box do tend to stick pretty hard.

This happens sometimes, but I think it's when the Swheat starts getting
old - it's my signal that it's time to change the box.

Odor control is good with this stuff.  In a very warm room, it will smell
a bit wheaty, but that's all.

I read a bit further in the thread, and environmentally this is a good
product.  It degrades well because it's a plant product, and is flushable
so it can go through the water treatment system in our town.  Some may
feel this is wasteful, but where I live they actually recommend that you
pick up your dog's droppings and put them down the toilet, so this makes
sense to me.  Although I originally purchased Swheat because I wanted a
scooping litter I'd be sure was safe with kittens, I like the fact that I
can flush it instead of carting it out to the curb.

the liter I use that works the best in these circumstances is Precious
Cat scoopable.  It's regular clay litter, but IMO, hold up better than
anything else.  And my Peewee is a side-squirter as well.

Swheat scoop has been wonderful for me -- it's the ONLY litter where
I've ever been able to peel clumps off the sides or bottom of the pan
intact.  Beats the hell out of Tidy Cat.  

The problem, for me, is that it's very dusty and coats my glasses every
time I clean the box.
