Well I am a new PBP owner, and I had no idea I'd get so attached! My piglet will be 8 weeks old tomarrow, I didn't get her to be a house pig, but so far that is were she is and at this point I've desided if she doesn't get distructive and uses her litter box (or goes outside to potty) I plan to let her stay inside! And as long as she stays non distructive I don't really care how big she gets. Most the ones I see these days are alot bigger then the ones I had when I was a kid, I'd guess Hilda's parents to be around 60lbs which I don't think is to bad at all, still smaller then two of my three dogs.
From what I have learned they make better pets if they are fixed (male or female). And for me the food was a challenge to get, I had to order it and it wasn't cheap (and she doesn't like it). May be easier for you (where you are will make a difference). They can be housebroke and kept inside, or they can be kept outside, good fencing is important, they like to root and if they root against the fence lines it can cause a problem. You will need a way for them to keep cool and a warm barn/shelter.
Right now having Hilda is alot like having a puppy, she has an area of the livingroom blocked off for her, it has a bed, food bowls, and a litterbox. She spends most her time sleeping on me, she's very sweet and affectionate. For a while I was the only one see liked and would scream her head off if anyone else tried to hold her, but I've worked to socialize her with as many other people as possible and she's now very tolerent of other people petting her, yesterday she suprised me by letting a girl she met for the first time hold and cuddle her (don't know if they are all like this, seems like one we had as a kid was friendly with everyone from the start and one other didn't care for anyone (even me who raised him)). She gets some free ranging time, she likes to harrass the cats and one of my mom's dog is her favorite to play with.
I don't know if that helps at all, but that is my newbie experience!
