I work at a seniors home and bring my animals in regularly.  Pets are great therapy for the elderly (and me too)!  It has been proven that the elderly actually live longer when they have a pet to love and care for.  I also have a granddaughter who stays with us about five days a week while her mom works.  I think she is fortunate to be growing up with animals and we bring puppies, kittens and baby goats to her class whenever possible.
