i under stand the reasons as to not house them together, as i said i don't have the room. And i rescued them from a guy that had them in a small glass tank in a laundry room with no heat at all in the middle of winter, I couldn't leave them there. i have tried to re-home them but every time someone says "ill take them" they never show to get them. if i put a divider in the cage the heat gradient would not work right. as for the stats, whats so bad about the zoo meds? i have 2 and 1 is over 3 years old and both work flawlessly and maintain a steady temp. there is two hides in there, but they refuse to use the second one. even if i physicality put one in each, one will move to the other so they are both in one hide.
