Hi Mrsant - we have pigs (I've never kept rabbits, even Fernies Current Bun trying to convince me that buns are superior hasn't takem me down The Rabbit Route
)
Pigs - must be 2/2+ piggies , they don't do solo.
2 females are easier, 2 boars are lovely but IMO harder work.
We have 2 sows and a neutered boar which is ideal for us.
They can live indoors all the while but the hay is messy (and smells more than the pigs)
Ours have an enclosed Pighouse (my DC old wooden playhouse that DH customised). In winter they sleep indoors and go out by day but they cannot go from a heated house to a cold hutch (or vice versa).
Some people do keep them outside all the while but you need to make sure they're protected and insulated ( against cold/damp/draughts. Also protect in summer against extreme heat)
And you need to go out in all weather to feed, clean, check.
Be aware of allergies (the commonest cause of pigs being rehomed after "kids got bored" ).
We had GP1 and GP2 (brothers) then GP1 and GP3 (boars) . DD was allergic to GP3.
We got GP4 and GP5 (sows) and neutered GP3.
Then GP3 died, we got GP6 (boar, neutered) she's slightly allergic to him.
GP1 was smooth, GP2 was abby, GP3 was Rex, GP4 is smooth, GP5 is smooth , GP6 is teddy. So I think it's the fur type with her.
But it took years for her allergy to show .
We love our piggies (and GP6 will be the last one though I said that about the ladies
)
