I have my hermans tortoise in a tortoise table with half covered in soil and half in sand , over which his lamp shines. One half of the table has a cover on it which is filled with hay. Whenever we take him out the soil seems very cold and he feels cold also. The temp in his bed area is about 65 degrees. His table isn't by a door or a window but it is against a wall opposite the radiator. He's very inactive and someone told me he may be cold and that I ought to transfer him to a viv. Does anyone else think along the same lines. I am quite happy to go out and buy him one if he is cold. I did try to warm the soil before putting it in under the lamp but obviously it hasn't retained the heat very well. Its the first time I have used soil as a substrate as I used reptiturf before but looked on the forum and eveyone suggested using soil. Is he cold do you think?
