Feline compulsive disorders including overgrooming, tail chasing, and pica cause significant welfare harm and often reflect underlying anxiety or conflict.
Compulsive disorders indicate chronic psychological distress, not merely quirky behaviour. Cats engaging in self-directed compulsive behaviours are experiencing reduced quality of life through anxiety, frustration, or conflict. Addressing the underlying welfare cause - often inadequate environment or social conflict - is more effective and welfare-positive than treating symptoms alone.
