hi, i've been here a little while to and it is fab! i started wit 1 a couple of months ago, and have 3 now, all boys. the 1st one was about 6 months when i got him, and he's very placid, gets on fine with others, then i got 2 babies a few weeks ago, one lives happy with my older boy, the odd squabble over the biggest bit of carrot or something, but nothing major, however the second baby has proven to be consistently aggressive towards the other two, one 8 mnts older, 1 same age as him. so i've kept him separate cage, where he can see the other for now, and am planning to get him newtered when he is 6 months old, ans pair him with a girl....lots of people on here seem to have done this, and they all tell me this works very well when they wont live with other boys, i keep hearing girl boy pair works best, although my boy boy pair do really well, and i know others do too, i'm in ireland, and the vet i have chosen to do the deed, is very very good, with experience with piggies-vip- , but they charge approx 100 euro here.....a bit pricey, but if he's gonna live for 7-10 years, i think it's worth it. when i got the first pig his first friend, he turned into a diff pig, sooo much happier, more relaxed with me and much friendlier, and they talk away to each other when i cant play! so i deff recommend doing what ever you can to get your new baby a buddy! good luck, you're gonna love being a piggie mum!
