Therapeutic Grooming
When your cat licks your hand during stressful times, they’re offering comfort. Journal of Feline Medicine research shows cats increase grooming behavior when detecting owner stress. This mimics social grooming in feline colonies, strengthening emotional bonds. Your cat uses this natural behavior to reinforce their role as your supportive companion. The rhythmic motion of their rough tongue stimulates nerve endings that trigger endorphin release in your brain, naturally reducing your stress levels.
