We have both
.
My boars aren't babies though, we got them last October from rescue (so I neatly avoided all the teen arsieness but I missed the cute baby pig stage).
My DD wanted a pet (she was veering towards hamsters, I steered her towards hogs.She wanted a boy, so we phoned a rescue who had a pair of brothers.And so it was)
We have a wooden playhouse that is 5'5" x5'5" which is lovely and cosy.DH fitted a light and heater, a metal mesh with fine mesh inside one window (so I can take the window out, but they are safe from predators and flies)
Last winter they came in at night (in the dining room, we have a 4'x2' cage but they got a bit narky after a coriander feast so we seperated their night cage). They went out every day in their Pighouse with hotwater bottles, loads of hay and a fan heater for 15 minutes to take the chill off .
I was out at 6.30am to get the house ready before work. They got a bit lairey stuck indoors -no lie in past 8am for me 
Boars don't tend to cuddle.Ours will sometimes sit snuggled. Or one will be under the hay ,the other on top of him
.
They've been out night and day since Easter. They have a big run for grass.
At the moment I use a light hay bed that I change daily (cardboard, newspaper and hay). In winter they have a deep bed (their haybox is 3' x3') so takes half a XL bag of hay (about £3.60 from the Range).
I spotclean the deep hay bed daily and completely clean every 3 days .
Mine wouldn't tolerate being indoors 24/7 because they wouldn't have the room, but I couldn't leave them out all the time.
GP1 sits on my DD bed and is a perfect gentleman
