Yea, you gotta have heat mate. Show your mum this thread so she can see for herself!!!!
Fester's setups are perfect. Heatmat under 1/3 or 1/4 of the clickclack, a hide each end, and waterbowl at the opposite end from the heatmat.... Pretty simple really, but without the heat he wont last long! Get in ya mums ear mate!
Good luck
