Cat friends, I am sure you and your cat in the baby happy days together, the cat's BB certainly let you add a little more 

 

trouble. Finally they have their cat training the consciousness of BB,but they have a mistake about e a new cat litter: 

1、Harmful components 

The article mentions: silica can cause chronic poisoning, and can cause silicosis.

We all know that crystal cat litter , also known as silica, the main component is silicon dioxide. This is common 

 

in the market we silica gel composition is the same. So whether toxic silica, we may wish to check it out.

There are two kinds of natural and synthetic silica, there are two kinds of crystal and amorphous forms. Nature of silica, 

 

also known as silica, crystal (quartz) and so belongs to the crystalline state, such as an amorphous diatomaceous earth. 

 

Industry, synthetic amorphous silica is also known as amorphous silica, synthetic amorphous silica, including silica, 

 

precipitated silica, hydrated silica, non-toxic to people and animals, ADI unnecessary to require (FAO / WHO, 1994), 

 

restrictions on the use of its content. Therefore, this silica can also be applied to a variety of industries, such as beer 

 

can be used as stabilizers (instead of formaldehyde), medicine and flow aid, medicine and disintegrating agents, thickening 

 

toothpaste, toothpaste and other wear-resistant agent. Especially as a desiccant, is the only U.S. FDA certification, can be 

 

used for drying food and drug industries.

Because, cat litter in a non-crystalline amorphous silica, amorphous silica from the entire history of the development point 

 

of view, so far without any caused by inhalation of amorphous silica leaving damage or loss of lung function cases. 

 

Silicosis (silicosis) is the most common form of pneumoconiosis type, is due to the long-term inhalation of dust containing 

 

free silica caused to a wide range of nodular pulmonary fibrosis based diseases. "To fibrosis factor" is the main cause of 

 

silicosis caused due to amorphous silica does not have the type of silica fibrous crystals, it will not cause silicosis.

Cabot Corporation USA conducted on amorphous silica obtained laboratory animal tests the following results:

From the mouth into the toxicity: In accordance with Section 772.112 44 FR 44054 - 21 part of the methods described, so that 

 

10 mice eat into the surface treatment of non-amorphous silicon dioxide, equivalent to 5g per kilogram of body inhaling this 

 

second silicon oxide. Result, all mice in the 14-day trials are to survive

Severe dust inhalation (4 hours inhalation weight): the 10 compiled a group of mice exposed to air containing amorphous 

 

silicon dioxide in the air the weight of amorphous silica concentration of 2.08 ml / l, test time is 4 hours, 4 hours and 

 

then observed for 14 days. As a result, 14 days 4 hours testing and observation period did not find dead mice. Anatomy of 

 

the mice also did not find any of their internal organs diseases.

Therefore, the above can explain, crystal cat litter is non-toxic harmless.

2、the  useless effect

The article mentions: Crystal Cat Litter permeable, small cat litter will flow to the bottom, so the best time to use a 

 

piece of cloth underneath the cat litter.

Here, we still want to talk about the composition and crystal structure of cat litter - amorphous silicon dioxide: As 

 

determined by its structural characteristics, as a kind of amorphous silica within the pore structure, that is, there are a 

 

lot of nano-porous . Mutual attraction between molecules together with the role, so this has a strong adsorption of silica. 

 

It can be in a very short period of time pet quickly exhaust discharge of urine and feces in the water; moisture absorption 

 

capacity of more than 80% of its weight and still maintain the appearance of dry. That, however, is unmatched by any cat 

 

litter.

That permeability, if not in the cat litter nest reached the required thickness, then when the cat urine, their urine will 

 

not be absorbed, which appeared to infiltrate the bottom of the phenomenon of cat litter, which both Which is easier for the 

 

cat litter problems.

Therefore, the only cat litter that has a permeability of crystal is very unreasonable to say.

Cat litter as a simple pet supplies and other things as are their respective advantages and disadvantages exist, there is 

 

effect size, price and poor, high and low price points, no one can fully comply with the requirements of each individual. 

 

Therefore, we find fault them unnecessary, have to distinguish a right and wrong. Not a word to say please? "Suitable, is
