You're about to hear all the same reasons I was told not to put dog poo in
the compost bin . See the "What to do" thread that started with my post on
1/31 /12 . Seems it all boils down to "there might be dangerous pathogens in
it since it is predator poo" . IMO , a properly working compost bin will
achieve temps that should kill those "dangerous pathogens" . And that sounds
better than allowing the rain to wash it all back into the soil ...
But can you guarantee that the temperature is hot enough for long
enough? That is, specifically around the feces.
Gardeners often get fairly up close and personal with their compost so
my primary concern would be contact infection.
In a world where some risks are better avoided, IMO avoiding this one is
the better choice.

Plus there is no upside to using carnivore crap. Carnivores like cats and
dogs produce very little waste because meat is a highly efficient food
source. Herbivores like cows and horses produce vast quantities of
partially digested plant matter which makes excellent fertilizer compost.
The bulk of cat waste is the kitty litter not the crap. You don't want
modern clumping litter anywhere near your garden, it turns into quick sand
and it never hardens or mixes with the soil. About five years ago I tried
dumping used cat litter into some groundhog holes on the theory that it
contains predator urine which would frighten the groundhogs. It was a huge
mistake, the litter turned in to sticky slurry and stayed that way for
years. I eventually dug it out and dumped it in the woods.

Honestly, you've never seen anything like it.
The use of human feces as fertilizer is a risky practice as it may
contain disease-causing pathogens. Nevertheless, in developing nations
it is widespread. Common parasitic worm infections, such as ascariasis,
in these countries are linked to night soil, since their eggs are in
feces. There have also been cases of disease-carrying tomatoes, lettuce,
and other vegetables being imported from developing nations into
developed nations.
Human waste may be attractive as fertilizer because of the high demand
for fertilizer and the relative availability of the material to create
night soil. In areas where native soil is of poor quality, the local
population may weigh the risk of using night soil.
The safe reduction of human waste into compost is possible. Many
municipalities create compost from the sewage system biosolids, but then
recommend that it only be used on flower beds, not vegetable gardens.
Some claims have been made that this is dangerous or inappropriate
without the expensive removal of heavy metals.
"Humanure" is a portmanteau neologism designating human excrement (feces
and urine) that is recycled via composting for agricultural or other
purposes. The term was popularized in a 1994 book by Joseph Jenkins
that advocates the use of this organic soil amendment.
Humanure is not traditional sewage that has been processed by
waste-treatment facilities, which may include waste from industrial and
other sources; rather, it is the combination of feces and urine with
paper and additional carbon material (such as sawdust). A humanure
system, such as a composting toilet, does not require water or
electricity, and when properly managed does not smell. Because the term
"humanure" has no authoritative definition it is subject to misuse; news
reporters occasionally fail to correctly distinguish between humanure
and "sewer sludge" or "biosolids".
By disposing of feces and urine through composting, the nutrients
contained in them are returned to the soil. This aids in preventing soil
degradation. Human fecal matter and urine have high percentages of
nitrogen, phosphorus, potassium, carbon, and calcium. It is equal to
many fertilizers and manures purchased in garden stores. Humanure aids
in the conservation of fresh water by avoiding the usage of potable
water required by the typical flush toilet. It further prevents the
pollution of ground water by controlling the fecal matter decomposition
before entering the system. When properly managed, there should be no
ground contamination from leachate.
As a substitute for a flush water process, it reduces the energy
consumption and, hence, greenhouse gas emissions associated with the
transportation and processing of water and waste water.
Humanure may be deemed safe for humans to use on crops if handled in
accordance with local health regulations, and composted properly. This
means that thermophilic decomposition of the humanure must heat it
sufficiently to destroy harmful pathogens, or enough time must have
elapsed since fresh material was added that biological activity has
killed any pathogens. To be safe for crops, a curing stage is often
needed to allow a second mesophilic phase to reduce potential
Humanure is different from night soil, which is raw human waste spread
on crops. While aiding the return of nutrients in fecal matter to the
soil, it can carry and spread a vast number of human pathogens. Humanure
kills these pathogens both by the extreme heat of the composting and the
extended amount of time (1 to 2 years) that it is allowed to decompose.

No offence Ian, but you do talk crap sometimes..
hugs and kisses
That's something you would do only out of desperation. Human waste is
doubly bad, first because closely related species carry common diseases,
and humans are by definition the most closely related species, and
secondly because humans are carnivores and carnivores concentrate all of
the diseases of the animals that they eat. The second reason is less true
for people than it is for cats because we cook our food, outdoor cats
don't. The rule should be don't use poop from an animal that you wouldn't
eat. We don't eat closely related species like chimps and we don't eat
carnivores or scavengers.
There are some cultures that practiced cannibalism until very recently,
the Fore people in New Guinea come to mind. They stopped because it was
the cause of the spongiform encephalitis disease kuru. AIDS crossed the
species barrier because Africans hunt apes and monkeys for food. Eating
any closely related species is a very bad idea as is eating carnivores and
scavengers. The only reason to do it is when the alternative is
starvation. China has a long history of famine so they do eat cats and
dogs, it doesn't make make it a good idea. In fact there was widespread
cannibalism in China during the Great Leap Forward when Mao starved 50
million people to death and there must have been cannibalism in the
Ukraine when Stalin deliberately starved 7 million people to death. Under
those circumstances the first thing you eat are the horses, then the rats,
then cats and dogs and finally people. This thread started about using cat
poop as fertilizer. Very very poor people use whatever they have on hand
including human waste, they do that because the alternative is starvation.
That doesn't make it a good idea for anyone who isn't living in a
desperately poor third world village. Rich westerners with their suburban
gardens should stick to manure from cows, horses (the French eat them even
if Americans don't), sheep and chickens.
I wouldn't but you can compost anything.
Wife's Aunt lost her eyesight working her little flower garden.
Neighbors cats had used it for a litter box. Despite washing hands she
got a horrible infection from brushing her hair away from her eyes or
She didn't use gloves of course.
I have forgotten the details except that cat poo had a very bad pathogen
in it. It's ot just tht or those cats but most cats.

Cat waste must be left to compost for at least eighteen months before it
is completely safe to use on edible crops. This eliminates the risk of
parasites like e. coli, tapeworm, and toxoplasmosis contaminating foods
grown in soil that has been enhanced with cat manure.
Clay-based, sand-based, and crystalline litters are not compatible with
use in compost, since they can damage your the structure of your soil
and cause synthetic toxins to leak into your garden. The best choices
for compostable cat litters are those made from natural, living
Plain sawdust is a wonderful, inexpensive, and delightfully green cat
litter that utilizes a wasted resource. Most cats love its texture and
will eagerly use a sawdust-filled litter box. However, it can sometimes
be difficult to find in urban and suburban areas, and some owners may
not be satisfied with the degree of odor-control it provides, especially
if they own more than one cat or do not plan to empty the litter box
frequently. It is an excellent option if you have only one cat and don't
mind a bit of extra work.
Another good option for an earth-friendly and compostable cat-litter is
a commercially produced litter made from pine or cedar. These tend to
have pleasant, natural scents, and they have been processed in such a
way as to be significantly more absorbent than plain sawdust. However,
it is somewhat expensive by comparison.
After adding the first layer of sawdust, soil, or leaves, simply dump
your cat's waste (feces or urine-clumped litter) directly into your bin.
Cover it with a one-inch layer of sawdust, soil, or leaves, and leave it
alone. When the time comes to empty your entire litter box, simply do
the same, and add another layer of your composting material. To speed
the composting process, it's a good idea to aerate the litter every few
weeks or months.
