I want to help this local couple who just lost their house to foreclosure. They have two Pot Belly pigs who are 9 and 6, a male and a female and they have two whether male Nubian goats. They are desperately trying to fond a place to board them. They already have their own large pen and houses with straw, etc. that will come with them. She will come out and feed and water and clean up after them except for 4 days a week when she's asking me to do morning feed for her only because she has to be to her work for like 7am and won't have time to come out here first. She will buy all their grain/hay/bedding. She wants to pay me $100 per month for board which is perfectly fine with me, that's my cable/phone/internet bill every month. Her goats are disbudded and everyone is up to date on things. She is a vet tech and runs a pet sitting buisness and also told me that if I ever needed any pet sitting it would be free or very cheap depending on the amount of time. I have never done this type of thing before and I'm a little nervous about it. Should I make some kind of agreement on paper, or like a lease or something? My 8 year old son adores pigs but I have no intention of having any of our own and these two are supposed to be really great with kids, the female has even done animal assisted therapy work and loves car rides and walks on a leash. I think it could really be a win win for everyone but I guess I'm just still a little nervous. I have heard horror stories about people boarding and then ditching the animals and stuff. She sounds really devoted to her pets though... Any advice?
