I have a 120 gallon snake cage. It is 4x2x2. It has been in use for two years and has escape proof snake lids w/ reinforced screen for cats. It is a great cage. It also has an undertank heater if you want. I also have one rated for a 40 gallon tank. Will post pics upon request. I am asking 75. Originally cost me 250 for tank w/ heating pad. Please pm me w/ any questions.
