Original thread HERE

I walked past the pet isle at the store and saw Tidy Cat Crystals.
I remembered the original thread, and took a closer look at the bottle.
I unscrewed the lid, and discovered there was no perfume.  At least not in this one.

I found a glass jar with a lid that seals.

I had an indoor/outdoor thermometer with hygrometer.
The outdoor thermocouple wire broke, which is why the outside temp reads "LO".

I sealed the hygrometer inside the jar and allowed it to stabilize.
Initial humidity is 49%.



Then I dumped some Tidy Cat Crystals directly from the store container into the jar.
After 24 hours, the humidity inside the jar went down to 28%.
Not too bad, except I used a rather large amount of crystals for such a small
container.



I took a regular glass mason jar and filled it with the crystals.
I put it in the gas oven at 300 degrees for 3 hours,
afterwhich I screwed the lid on and allowed it to cool overnight.

Today when I opened the jar, it had a very strong vacuum from the hot air cooling.

I dumped some into the test jar with the hygrometer, and within 10 minutes the
humidity dropped from 49% to less than 20%.  

Lesson here is that before this kitty litter is used for anything you consider
important, it needs to be oven dried first.



The brown colored crystals isn't because I did this with used litter.
Sources on the web seem to indicate some crystals may be contaminated with
some organics which char in the oven.  

Awesome!

That must be a hell of a pet place!

I'm not the English teacher in the family.  Wife says it is "aisle".

Who the hell comes up with spellings like that.
