Cats can provide benefits to those in retirement homes and facilities for people with dementia. Some cats, like Oscar in the US, have shown extraordinary empathy towards weak and elderly residents, reducing loneliness and being a source of joy. While there are potential negatives like allergies or damage to furniture, on the whole cats can provide companionship, a calming influence, and a sense of continuity for residents in their later lives. Facilities must consider responsibilities, sanitation, and what happens to the cat if its owner passes away.
