Why does my house smell like cat urine when there is no visible mess?
Pet urine soaks into hidden areas like subfloors and rugs, releasing airborne vapors that circulate through the entire house. Because the source is often invisible to the naked eye, standard surface cleaning fails to clear the odor from the air, leaving the whole home smelling like pee.
