PARO Therapeutic Robot (baby harp seal)
The FDA-cleared therapy seal — for facilities, not families.
Our take
PARO is the robot pet with the most research behind it and the only one cleared by the FDA as a Class II medical device. It is sold by quote to hospitals and care facilities at roughly $6,000, learns its name, and responds to touch, voice, light, and temperature. The evidence is more modest than its reputation: the largest trial found better engagement and mood but no difference on the standard agitation scale, and people with severe agitation responded poorly. For a family, a $160 Joy for All is the realistic comparison.
Best for: Memory-care units and hospitals with a program budget.
