Today I went up stairs where I will be putting my new cage and It was really cold. Then I asked my mom and we looked around for a heating vent. Their was one but it was blocked off by the people who lived in my house before us. The sad part is that I don't have any room in any of the other rooms to put my cage except for my old room which can only hold a 2x4. I am soooo mad. Do you have any ideas of what I can do or what is the lowest tempature a cavy can live in. Thanks Queenie
