FK1
Cats, Dogs, small pet furries, chickens, ducks, geese, pigs (no experience with breeding though), goats & sheep.
Could probably manage cattle (can hand milk). Can help with horses- though not with exercising, but can feed, water, muck out, deal with farriers etc.
I refuse to look after pet spiders, and would be reluctant to go into your house if you had such things!
