Hi Shed-owners.... I'm new to this forum. We have 3 piggies who have been living in an outdoor hutch since March. Last month, I built a C&C case set up in our shed, as I couldn't fit the hutch through the narrow door. I've got cortex plastic on the floor for insulation, with a thick furry insulated vet fleece on top. Each biggie has it's own cat littler tray, filled with moisture-wicking megazorb, hay and a wooden house stuff with hay (so no territorial bickering whilst cooped up indoors over the cold wet weather). I've put fleece blankets and aluminium insulated blankets around it and am putting snuggle safe heated pet pads in on top of the wooden houses for them each night but I'm still worried about the cold. My shed has no electricity - I wanted to put a paraffin or gas heater in there but was worried about fumes. Any advice much appreciated?
