Only if it's not too much trouble, mate. I have a great interest in the different ways that animals are used to help us humans, stemming from being in the middle of my Psychology degree.
I've seen TV programs where elderly people will come out of a catatonic state or really sick kids will actually smile while they bring a 'wellness pet' into a nursing home or hospital. Having pets is supposed to lower your blood pressure too - even goldfish!
They train monkeys to help out physically disabled people too, I think.
