Most of it I understand.

I am surprised people have to phone ahead to bring in a pet for a visit.

I routinely take my pets to hospitals, nursing homes, adult day programs == wherever my Dad happens to be. I don't call first, just walk in with which ever cat or dog I have.

The rest of it - pets up to date on shots, not aggressive or dirty, washing hands after petting, - all normal for a health care place.
