I have a couple questions about my Argentinian Red Tegus First of all let me tell you about him...We bought him from a pet store he was small when we got him, he was missing the end tip of his tail and a finger. (the lady said he got into a fight with another lizard) So, we bought the bedding and had everything set up nicely. PEEEWWW !!! The tank is at the end of our bed and we are very busy people so we only changed/cleaned the bedding once a week most the time we actually put the lizard in the tub and he would swim around and defecate in the water so his bedding stayed fairly clean. That got a tad expensive so we bought some outside carpeting the kind that looks like fake grass its kinda plastic like so is rinses/washed easily. Also at first we were feeding crickes/little bitty no hair mice and hardboiled eggs. But then we started wasting money when he wasnt ready to feed and the crickets would die, and the pet store was always out of crickets so we basically have just been feeding hardboiled eggs for almost a year. Here comes the questions, is the diet/housing we are using harming our lizard? And we went camping in about october and lizard layed next to us on the upturned grill lid, when we woke up he was very cold and there was a giant red sac hanging out of his butt, he had also pooped everywhere. We brought him home immediatley warmed him up and about 12 hrs later the red sac was gone. We never figured out what happened or caused it but he seemed better. Also during this time he has went from energetic to almost dead seeming. So its December now, he has been a very lazy lizard not eating or drinking never even see him awake (we work alot). We were cleaning his tank and put him in the tub with warm water thirty minutes later we go to get him and his is very cold, and lifeless, tounge was greyish not pink wouldnt open eyes seemed dead, blew air into his nose water bubbled out of his nose set him in his tank under the light....he lived but hes still very sluggish keeping his temp at a good 70ish level hes staying warm enough but the other day his light went out while we were sleeping and when we woke up he was freezing cold and the red sack was hanging from his rear again. Again there was feces all over him. Can someone please tell me what the red stuff is and help direct me to a health lizard life?
