Ho ho! Friends with a big garden (and a stream) bought a goat when it was found their young son was allergic to cow's milk - another lifetime when other milks in a supermarket was science fiction.
I used to look at this, have a go at milking (the nanny wasn't impressed) but thought having a goat might be a doable enterprise. Then we were taken to visit another goat owner couple - who kept their *herd* in a downstairs bedroom of their *rented* property. I shall not mention the smell.
