Flushable or Not Most litters cannot be flushed down the toilet so check the labels if you want one that is biodegradable and flushable. Otherwise, it's best to scoop it into a plastic bag, close it with a knot and dispose of it in the garbage. Some pet stores offer litter in bulk to hold down cost. It comes in large barrel-type containers and you scoop it yourself into a smaller container to take home. Miscellaneous Some litters are especially low in dust if that is preferable either to you or your cat.
Some people use regular sand in litterboxes.
Since some outdoor cats enjoy using sandboxes, this can make sense. However, sand doesn't clump and is quite heavy. You can use more or less depending on your cat. Too much litter can cause your cat to sink into it or make it more likely that he will kick or track it outside. Too little litter may cause the bottom of the box to become easily soiled.
