I have a 10L click-clack that ive soldered vent holes in (and only burnt myself once!), and a perch too. im going to put down paper towel as substrate, 2 toilet rolls as hides and a ramekin (sp?) for a water bowl. the next thing before i get my snake is how do i heat it? I was thinking a heat mat and one of those point-and-click thermostats but i am rather limited by funds. what should i get? what brand model, price, etc...
