I was at wl-mart today, and saw a plastic tub that looked liek ti would make a good cage. Buying aquariums is getting expensive so I thought it was worth a shot. The container is about a 1 ft tall, and 4 feet long give or take. It has a top that snapped on tight, but i'll need to secure it around the center where it lifts up easily. The only thing i don't understand is how can I heat the container? I plan on cutting small holes in the top, and making it breathable if that makes sense). How do i heat it though? I figure using a uth is out of the question, so would a heat lamp work ok? and how can i gage heat in the plastic? Any help is appreciated.
