Episode notes
Cat Holes Depend On Soil Biology
- Cat holes only work where soils have active microbes, moisture, and organic matter to decompose waste.
- Alpine, desert, and dry soils often lack that capacity so buried waste can persist for months or years.
Hydrology Spreads Contamination
- Water movement can carry buried fecal bacteria into streams and lakes via runoff and shallow soils.
- Even properly dug cat holes can contaminate water if they are hydrologically connected to surface flow.
Pathogens Persist In Cold, Dry Soils
- Cold and dry soils preserve pathogen viability for months to years, creating contamination reservoirs.
- This elevates human waste from personal hygiene to a potential public health issue in high-use areas.
