First, the pix- I can never get the pic uploader on here to work, so I'll post the links to my fb pix. https://www.facebook.com/photo.php?...4702140.-2207520000.1364590059&type=3&theater https://www.facebook.com/photo.php?...4702140.-2207520000.1364590059&type=3&theater As you can (hopefully lol) see, the cage consists of a large and a small cage sitting on top of an identical large and small cage. The dimensions are as follows Total Cage dimensions: 54 in long X 22 in high X 17 in wide Small Cage dimensions: 18 in long X 22 in High X 17 in wide Large Cage dimensions: 36 in long X 22in high X 17 inch wide I dont want to cut the cage, or screen portions off, so using lights or Ceramic heat emitters innt going to work. The previous owner said he used heat tape, and I plan on doing the same. I have never used it before, so I need a little advice here on how to use it. Ive read through several posts on here and have seen people say cover 2/3, 1/3 and even 1/2 of the cage. Which is true?? The cages will be used to house california king snakes, and one of the larger ones will house my ball python Henry. My questions are: A) How long of a strip do I need to buy? The two cages on each section have a sealed hole that I could run the tape from one side to the other. B) How much of the floor space do I need to cover? C) Could I place the heat tape directly on the wood? D) Can I cover the heat tape with a sheet of plastic, and seal it around the edges? E) Can I buy the heat tape used for plumbing, or is there a reptile specific one that I need? Thank you tons people!
