Its a year and half old...4 feet on the dot, 10.75 lbs. Hes tame as puppy, my siamese kitten cuddles up with him and falls asleep, its hilarious to watch. I got him as part of a "Pair" that turned out to be two boys...whoops, but anyway thats why I'm selling him. He's really 'informally' for sale...I'm not really in a huge hurry to get rid of him. Anyway - I'm looking for around $400. He's a blue tegu by the way not an argentine black and white (its a closely related species, but smaller, he won't get much bigger than he is...of course that said he's pretty freakin big).
