I found someone selling an 8 foot tall, 8 foot wide, 8 foot long reptile cage for dirt cheap! The cage is plexiglass with wood trim, no screen at all. Would this work for a cage since it doesn't have a screen top or would it still let out to much heat/humidity? I could cover sides to make it feel more secure. Let me know if this would work or not, it's close to my house and less than $40, the guy really wants it out of the garage.
