I rescued one about 2-3 years ago when I left the day care I was working at. they were seriously terrorizing and neglecting this animal. it is unfriendly and a huge PITA. but I keep plugging along with it, once we get pets, we have a hard time getting rid of them. we dont, actually....
(no judgement, there, I actually wish I could bring myself to give up a few pets we have now, they may get more than just care, they may get a loving home..but oh well)
it requires care more than three times a day, whether its change of water, food refills, etc. I change the bedding at least once a week, and it still smells up the room (it is in a rubbermaid 'gift wrap' size tub which is probably 2 feet by 4 feet at least) plenty of room for the one pig. three times as big as what it was in at the day care. we use pine chips I get at the feed and seed. I also have to buy pellets, timothy hay, and various fresh fruits and veggies (extra spinach and romaine, but otherwise just scraps and leftovers of ours) we really cant afford it. it isnt cuddly (I wouldnt be either after being abused by preschoolers and toddlers) and pees and poops everywhere. it also needs to be bathed a few times a month, or else. its nails need trimmed.
way too much info, more than you asked for, I know. but this pet has been very frustrating and lots of work and money for us ove rthese last few years, with almost no payoff.
The bedding doesnt get all over the house, except when I am cleaning and changing it...then its pretty messy. personally, I dont know why anyone would get one of these. But I know alot of people love them and enjoy them as pets. of course, i am leanign towards a no pet household, as any animal in a cage upsets me lately.
also, I let my neices play with the pig, but I am so nervous, as I read that they can be very fragile. if you grab a certain spot on their back, they cant breathe, and if they fall even a short distance (or are dropped) they can easily break their legs or back
so they dont even seem like a good kids pet. especially considering all the care they require.
so I am super careful with it around my 17 month old, and keep the cage away from her.
good luck. I dont mean to be a downer, I guess I needed to unload my guinea pig woes.
