The nursing home my wife works at has a cat and employees bring their dogs in on occasion. They are allowing in person visits now. Resident and visitor have to sit outside, across from each other at a table 6 foot across. No human touch but it’s better than nothing.
Residents in my MIL assisted living home have dogs and cats...plus one of residents feeds feral cats outside...but place only has 35 apts.
I’ve worked in nursing home and have seen elderly people light up when a dog or cat is put in for a visit. What REALLY makes elderly people light up, especially women are babies. Boy, when ever a baby is bought into a nursing home the old dears really start smiling.
