Evidence-based guidance on when and how behavioral medications improve welfare in cats with anxiety disorders, compulsive behaviors, and inter-cat aggression.
Behavioral medication for cats represents a significant welfare opportunity that remains underutilized due to owner reluctance and veterinary hesitancy. Cats with anxiety disorders, compulsive behaviors, or inter-cat aggression experience genuine psychological suffering that behavioral modification alone may inadequately address — particularly when anxiety is moderate to severe. Anxiolytic medications work by reducing the baseline anxiety state that makes behavior modification difficult: a cat that is chronically over-aroused cannot readily form the new positive associations that counter-conditioning requires. The welfare cost of undertreating cat anxiety is substantial: cats may hide chronically, avoid social interaction, develop stress-related physical illness including cystitis and over-grooming, or exhibit aggression that results in rehoming or euthanasia. Veterinary behaviorists emphasize that medications are not a substitute for environmental management and behavior modification but can provide the pharmacological foundation that makes other interventions effective. Welfare-centered veterinary practice requires honest assessment of anxiety severity and willingness to recommend medication when indicated.
