Yesterday I bought some cat sand from target to put into my hedgehog's litter box. I was pretty sure that it was nonclumping. It didn't say nonclumping, it said something that started with a c (it was not clumping) I think it means nonclumpling. When I got home I tested it to make sure that it was nonclumping by pouring water on some of it. When I did it made a faint fizzing sound. It is now the next day and it still hasn't dried, the few bits that have are hard and crumble as soon as you touch them. I would like to give the exact name for what it was called, but the bag it came in is out in the garbage can under the grass clippings. Please let me know if anyone knows what this is and if it is hedgehog safe or not.
