Even if you have a fervent litter burier, the grass litter will not cause any injuries or damage.

It is also naturally clumping and prevents odors, although it does benefit from some enhancements in these areas.

This combination does a good job of masking smells, at least until the clumps fall apart, but can be quite strong smelling initially.
