I think Tegus are intelligent and social animals. They have a need to interact with other Tegus. Like others in this forum I am trying to provide the "best" for my Tegus. After thinking about balancing their needs for sunlight, fresh air, etc. I came up with the idea of using an old bird cage. The bottom and about three or four inches on the side I covered with cardboard. What do the Tegus think? I think they like it. They are taken out in the cage, a little awkward, but it works for me. Once they are settled they bask and survey their surroundings. They DO NOT like the dogs, no matter how much they smile, drool and pant. Lucky for me the dogs are trainable and just like when you acclimate a new puppy eventually the dogs will leave them alone.
The idea of housing my Tegus outdoors is one I am going to pursue. An eight foot horse tank is just about right for what I want. Most of us would agree that we would rather have a Tegu that acted like a Tegu rather than one that acted like my Llewellin Setter. If that means the Tegus are a little flighty at first...as long as they will settle down and not bite.
As far as good holding reptiles go...the bullsnake I traded for my rufescens was a better holding reptile. That doesn't mean I am giving up on Tegus. I am fascinated by them. I will continue to try to meet as many of their needs as I can. Hopefully, along the way they may think enough of me to reward me for my efforts. Until then, two Tegus chasing crickets is way more fun than watching TV.
