I agree with everything said on the pros for plastics. I just love being able to look into my cages and see my pets. All of my reptiles are housed in wood cages with sliding glass doors. The cost me a fortune, but they seem to be hands down the best way for me to care for my herps. I also like the option of locking the glass if need be to keep my other pets and children out. I have pics of all my set ups on my website. They are not the most attractive or easiest to work with, but do a great job of showcasing the animal. I love my pets and strive to take the best care of them, however I also enjoy just looking at times. We have about 5-10 kids come in our house a day to see what the reptiles are doing and glass fronts are perfect for allowing children to look and not touch. Shannon and I just work a little harder on the husbandry. We probably put at least 3-4 hrs a day into our pets between the two of us.
