I adopted two boys from there and cannot be happier. They are healthy and have been looked after extremely well before being adopted out. The ACS care for neglected and unwanted guinea pigs. All food and vet expenses comes out of their own pockets. They rely on volunteers and donations. The forum is great, everyone is very friendly and is a great place to get advice or just chat about guinea pig stuff. I highly recommend the Australian Cavy Sanctuary if you are interested in buying a guinea pig.

Approximate cost: $20
