Inappropriate elimination is a leading cause of cat surrenders to shelters. Understanding the medical and behavioral causes helps keep cats in homes and improves their welfare.
Inappropriate elimination often reflects underlying medical problems or significant psychological stress. Cats experiencing pain during urination from cystitis or infections associate the litter box with pain, creating learned aversion that persists even after the medical condition resolves. Cats in chronically stressful environments develop stress-related lower urinary tract disease. The welfare implications extend beyond the physical symptoms to the severe stress of living in an environment where basic elimination needs become sources of anxiety and pain.
