Maybe this might help?

I used to take my ferrets to the nursing home to visit my oma and opa, and all the old folks just loved them to pieces -- my opas eyes would always light up when he saw i had brought them out, and several of the older folks would always ask after them. All i did was clear it with the nursing home before I started doing it, and always had copies of their vaccinations with me. Unforatunatly, what with both of my grandparents passing on, and one of the ferrets as well, I haven't had the heart to go back, but probabally should.

I think the vaccinations, permission, and possibly insurance might be needed? If you can join an organization that already does this, then you might be covered by their insurance as well
