I am pretty sure that the kind I have is the same; probably just a different locality name or something? It is the same as the Feline Pine, but that seems to be more expensive because it is at our local grocery store; whereas the equine stuff is in a bigger bag at our feed store.
I would like to try that CellSorb bedding that alot of people use, but I have not seen it in any stores and shipping on a bag would probably give me a heart attack.
