Well.. Ive did pretty much what i could, im looking into another contoller or maybe a set of nice duals maybe johnsons or ranco. Basiclly whats going on is that the cool size ranges from 73- 77 cant get it higher today in the morning it was at 73 i decided to put aluminum foil from under the flexwatt stretching across the plastic container (hoping it might help) I also have the lower portion of the container wrapped in my sweat pants and the whole set up is sitting on a warm sweater. I can currently seeing the temps going up slowly now at 75.5 on the far coldest end. Im considering going with another container that has more floor space because i kinda messed up with the one i have now. Its way too small after everything was put in it. So she doesnt really have much floor space, do you think i should just let her sit this week out in this one and then get a larger one? also in regards to the temp. what do you guys recommend? and i dont understand how you guys feed them .. i feel like such a murderer! i have 2 baby mice and i feel so bad you have no idea. Im going to try to raise them because i cant just kill them.
