Hi, we are thinking of getting 2 GPs for our twins to be a first proper pet. Me and OH both grew up with loads of animals so are prepared for what this entails. The bit I am unsure about is indoor or outdoor housing. I had thought ( I think mainly because I am used to having rabbits which we had when I was a child) that they could live outside all year. However I keep reading very conflicting things online about this ranging from that they need to be indoors if it dips below 10 degrees C (we live in Newcastle, that is most of the year!) or that they are fine outside if you insulate the hutch properly.
I was thinking of getting a substantial and well-insulated hutch with a cover and run for outside and a cage for inside and keeping them outside most of the time but moving them in say November-Feb when it got properly cold but still taking them out to the run in the day. They could either go in the utility room (next to kitchen) or in the garage but that doesn't have natural light although we could keep a light on. My main worry I guess is that whilst we have lots of space outside we don't have as much inside. Any guinea pig gurus have any advice.
