Hmmm. Would this product be available in different absorbancies and thickness? Or would they be labeled "Smelly", "Extra Smelly", and "Deadly"? The "Smelly" size would be about 1" thick, the "Extra Smelly" size would be about 3" thick, and the "Deadly" size would probably have to be about 6" thick.

Also, wouldn't the force of the blow knock them out of place and thereby render them ineffective?

These are just some kinks--I mean stinks--to work out.
