Hi guys, in the UK it is so cold at the moment, like -8 at night but the cold front has broken and expecting lows of 0 degrees this evening. The piggies are in the garage in a large hutch, which is insulated with a thick woken tarpaulin with two duvets underneath. In the bedroom area they have a tubular heater, a guniea pig tee pee bed thing and a snuggle safe heat pad which I reheat morning and night. Will they be okay? I'm worried about them!
