as a new piggie mummy I would like to know those of you who have piggies that go outside, at what time of the year (I'm in the UK) do you stop putting piggies on the lawn? what temps can they cope with and when to think about letting them have floor time indoors rather than out on the lawn? I would idealy like to put them out for a couple of hours a day as long as its dry....mine seem to love being on the grass and they have only been with me for 3 weeks, previous owners only had a hutch and they did not have acess to a lawn area. thanks.
