Not to worry.

I have invented a filter that eliminates methane from biological gas releases.

The filter is inserted into the anus, but it is actually very comfortable…even pleasant feeling.

When gas is released, the filter literally “burns” the methane gas. The temperature of the filter rises to 120 degrees or perhaps higher depending on the size of the gas release.

The burning smell does not seem to mask the natural odors.

The anal filter can be used in cows, but someone will have to run out and re-insert the filter every time the cow takes a dump.
