So I am extreemly interested in getting either a savana monitor or a columbian tegu and have started my research. I know that the enclosure for these animals is quite large but what is the recomended size for them? I know that they need to beable to burrow down but is it preferable to build the burrow yourself or just let him do it? lots of questions and I dont have tons of time to research at home due to lack of internet and phone reception where I live but I have my lunch hour and the ability to print from work. thanks.
