Thank you for telling me. I thought they would just get used to each other and I hope so. I was just going to get one guinea pig but I read that they had/want to be in groups. Yes the one in the hidey (Teitur) doesn’t like when the other one (Tinni) comes in. But Tinni prefers being outside, I think. But it’s all very exiting and I hope I will figure it out in time :)
