Junior Guinea Pig
I just put one in the microwave and could smell burning. I put it in with the cover on as it says you can. I got it out and could smell burning strongly. So I examined it and looked at the pad. I seen it was burned and seemed to be leaking. I thought no please dont be broken. But no the heat pad is ok but the cover had burnt into it. The cover was a homemade one. So the velcro you can buy in the shops does not stand the heat like the covers from the manufacturer I think. So I would say TAKE THE COVERS OFF.
