I have a 13ft long by 7ft wide outdoor cage. It is 6ft tall. Is this large enough. Also how could I heat it during the winter. If I put up walls would a space heater suffice. Also for an indoor enclosure what would be the right size to use. Would a 10 ft by 5ft be ok. Also anyone interested in 1 year old male argus, perfect health, would make a great breeder. Need the space, if anyone knows someone who wants an argus, just say so. Thanks
