Normally I buy kitty litter in a bucket (easy to carry.) But I was recently shopping with a friend, and he spotted some bags of litter, very inexpensive, and offered to carry them for me. It was a name brand, so I decided to give it a try. Unfortunately, I did not read the label, and discovered, to my dismay, that is is not clumping litter. When wet, it just turns brown and stays wet. And, strangely, it smells like peppermint!
Today I was reading an article about "The Most Toxic Places in Your Home" on Today / MSNBC. The article mentions that many kitty litters contain crystalline silica, which is a carcinogen. Great, now another thing I have to look for on the label!
Darn stinky cats.
