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.
Our take in full, what's good, what's not
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.
- FDA Class II clearance; two decades of use
- Most studied robot pet in dementia care
- Antibacterial fur; day/night rhythm
- ~$6,000, quote-only, institutional
- Short battery; motor noise; no body warmth
- Evidence is mixed once you read past the headlines
Who it's for
Memory-care units and hospitals with a program budget.
Who it's not for
- Short battery; motor noise; no body warmth
- Evidence is mixed once you read past the headlines

- BMC Geriatrics 2019 scoping review of PARO benefits/barriers in care settings; multiple hospital feasibility studies (e.g., Geriatric Nursing 2020; Dementia 2021)
- Used in Japanese nursing homes since 2004; adopted in Danish municipal elder care and pilots in US/Canadian hospitals (per literature)
- Japan's Ministry-recognized 'care technology' selected device for dementia care (ResearchGate summary, 2025)
How we know this, and sources
Specs and prices come from the manufacturer's own pages and press releases, checked on September 5, 2026; owner-reported limitations come from published reviews and caregiver forums. We have not yet tested this unit hands-on — what that means. Price confidence: low. Confirm on the manufacturer's site before buying.
Price note: No published US price — sold by quote through PARO Robots U.S., primarily to hospitals, nursing homes and care facilities. Historically ~US$6,000 (ABC News, 2011); third-party 2026 guides cite ~$6,100. Japan list ¥423,500 (1-yr warranty) to ¥495,000 (with 3-yr maintenance pack); Japan lease ~¥13,000–15,000/month via Daiwa Lease.
