We've got:
Groups of 4 sows with 4 water bottles, 4 food bowls, 2 hay tunnels, 1 large fiddlesticks bridge, 1 small fiddlesticks bridge, 3 string/wicker ball things, set of 3 loofah type chew toy things, wooden bridge and a slightly raised hay area made from one of those really solid pieces of cardboard packaging you get in boxes with new mobile phones and their chargers an accessories (but bigger - I think it came with our steam mop).
Pair of sows with wooden hay rack, 1 hay tunnel, small fiddlesticks bridge, large wooden house, water bottle and food bowl (they are sisters with very close gentle bond so no issues with sharing food and water).
Pair of boars with water bottle (that they never use!), 2 food bowls, fleece lined snuggle bed, straw hidey, chube, separate fleece floor area (they are in a hutch with mainly sawdust - the girls all live inside and we didn't want to start the boys fighting if they smelt the girls).
Have ordered some snuggle sacks for some of these lucky piggies - can't wait!
