There's the guinea pig cages forum, it's American, but I'm to chicken to post there, they seem nice on the whole, but it doesn't seem as friendly as here if you know what I mean. It's also reallllllyyyyyy slow too but there is some good info on there. There are also the guinea lynx forums too xox
I don't really like guinea-pig cages forum personally, although the website does have some great information I am also a member on Rodents with Attitude and Guinea-Pig Haven
I agree with you guys. There's plenty of really good information on there, but as I'm an owner that keeps her pigs outside most of the time, I'm like the spawn of the devil over there . I daren't join up cause I've a feeling I'll just be made to feel like a completely inadequate guinea pig owner, even though in 18 years of owning guinea pigs, not one has had problems relating to living outside... and all but two of them have lived at least 5 years (most 6-7 and one 9 year old!).
I wasn't going to join a piggy forum until I came across this one. You're all unbelievably supportive and friendly to everyone here!
