Pigs living in the house will need their own space, preferably their own room. It is advisable to have the pig area away from the kitchen so the human family can eat in peace. They like to burrow under blankets or hay to make a nest for sleeping. Many people have slept with their pigs but pigs can be very moody, pushy and possessive about their sleeping area.
If your piggy lives outside, a porcine companion is very strongly recommended. Pigs love to snuggle together when sleeping.
Outside pigs need a house that will be cool in summer and warm in winter. In areas where the temperature is much below freezing for long periods of time a heat lamp is desirable. Pigs need a swimming pool or wallowing area for hot summer days. Pigs do not sweat or pant, and need a bathing area to keep cool.
The yard or area where your piggy will stay needs to be securely fenced. If you live in a populated area the piggy will need to be kept from wandering. That sensitive sense of smell will be able to detect a good dinner blocks away. In addition fences are necessary to keep dogs and other intruders out. Hog panels, cedar fencing, chain link fence, and electric fencing have all been used successfully. Hog panels are the most secure but can be expensive for large areas.
It is absolutely not a good idea to tie a pig. Pigs are prey animals and when frightened will panic if they are restrained from running. This panic can be life threatening as the pig attempts to get free from the rope or chain and works itself into a frenzy.
When deciding where your piggy will live it is good to consider ease of access. Pigs have difficulty with stairs as they reach maturity. Piglets can leap onto a couch and negotiate steps with ease, an adult pig can't.
